In that location are 7 types of electromagnetic radiation which are given in the  list below:

• Light
• Infrared radiation
• Microwaves radiation
• X-rays
• Ultraviolet radiation
• Radiowaves
• Gamma rays

What is Electromagnetic Spectrum?

The word spectrum comes from a Latin word meaning "course" or "appearance". Other familiar words from the same root include "spectacle" and "species." Newton introduced word to describe the rainbow-like image that resulted when a beam of sunlight passed through a glass prism. Today we speak of the electromagnetic spectrum to indicate the many different kinds of electromagnetic radiations,classified according to their frequency or wavelength on a calibration from large to small. We also speak of the political views on a scale from ultraconservative to ultra-liberal.

In Maxwell's time, light and the adjoining infrared and ultraviolet radiations were the just known types of electromagnetic radiations. Today the electromagnetic spectrum includes a broad range of different kinds of radiations from a diverseness of sources.

From  Maxwell's theory, we conclude that even though these radiations differ greatly in their properties, in their means of production, and in this means we observe them, they share other features in common: they phone call tin can be described in terms of electric and magnetic fields, and they all travel through a vacuum with the same speed (the speed of light).

In fact, from the fundamental betoken of view. they differ only in wavelength or frequency. The names were given to the various region of the spectrum. I accept to do only with the way the unlike types of waves are produced or observed; they have null to do with any primal property of the waves.

Other than the difference in their wavelengths, there is no experimental way to distinguish a wave in the visible region from one in the infrared region; the waves have identical forms and identical mathematical descriptions.

There are no gaps in the spectrum, nor are the precipitous boundaries betwixt the various categories. (Certain regions of the spectrum are assigned past law for commercial or other uses, such as Goggle box. AM . or FM broadcasting).

seven  types of electromagnetic radiation

1. Light The visible region of the spectrum is the one about familiar to the states considering every bit a species we have adapted receptors (optics) that are sensitive to the most intense electromagnetic radiations emitted by the Sun, the closest extraterrestrial source. The limits of the wavelength of the visible region are from about 400 nm (violet) to near 700 nm (red). Light is often emitted when the outer (or valence) electrons in atoms change their state of motility: for this reason. Such transitions in the state of electrons are chosen optical transitions . the color of the low-cal tells u.s. something nearly the atoms of the object from which it was emitted. The written report of the calorie-free emitted from the Sun and from distant stars gives information about their composition.
2.  Infrared. infrared radiation, which has wavelengths longer than the visible (from 0.7 μm to almost 1 mm), is normally emitted by atoms or molecules when they change their rotational or vibrational motion. Often this alter occurs as a change in the internal energy of the emitting object and is observed as a modify in the internal energy of the object that detects the radiations. In this example, infrared radiation is an important means of oestrus transfer and is sometimes called estrus radiations .
3. The warmth you lot feel when you lot place your manus well-nigh a glowing calorie-free bulb is primarily a event of the infrared radiation emitted from the bulb and captivated past your hand. All objects emit electromagnetic radiation ( called " thermal radiation;" of the extended text) because of their temperature. Objects of temperatures in the range we ordinarily meet (say. 3 G to 300 G )emit their most intense thermal radiations in the infrared region of the spectrum. Mapping the infrared radiation from space has given us data that supplements that obtained from the visible radiation.
4. Microwaves.  Microwaves tin can be regarded as short radio waves, with typical wavelengths in the range of 1 mm to 1 m. They are normally produced by electromagnetic oscillators in electrical circuits. As in this case of microwave ovens. Microwaves are oft used to transmit telephone conservation: show a microwave station that serves to relay telephone calls.
5. Microwaves besides reach us from extraterrestrial sources. The well-nigh abundant component is the microwave background radiation, which is believed to exist the electromagnetic radiation associated with the "Big Bang" fireball that marked the birth of the universe some x¹⁰years ago: as the universe expanded and cooled, the wavelength of this radiation was stretched until it is now in the microwave region, with a top wave, length of about 1 mm. Neutral hydrogen atoms, which populate the region between the stars in our milky way, are another common extraterrestrial source of microwaves, emitting radiation with a wavelength of 21 cm.
6. Radio Waves. Radio waves accept wavelengths longer than 1 m. They are produced from terrestrial sources through electrons aquiver in wires of electric circuits. By carefully choosing the geometry of these circuits, every bit in an antenna. Nosotros can command the distribution in infinite of the emitted radiation (if the antenna acts as a transmitter) or the sensitivity of the detector (if the antenna acts as a receiver). Traveling outward at the speed of lite, the expanding moving ridge-front of TV signals transmitted on Globe since about 1950 has now reached approximately 400 stars, carrying data to their inhabitants, if any, most our civilization.

Radio waves achieve united states of america from extraterrestrial sources, the Sunday being a  major source that frequently interferes with radio o TV reception on Earth. Jupiter is likewise an agile source of radio emission. Mapping the radio emission from extraterrestrial sources. Known as radio astronomy, has provided information about the universe that is ofttimes not obtainable using optical telescopes.

Furthermore, because the Earth's atmosphere does not blot strongly at radio wavelengths, radio astronomy provides sure advantages over optical, infrared, or microwave astronomy on Globe.

A typical effect of the observation of our milky way at radio wavelengths. One of the virtually startling discoveries of radio astronomy was the existence of pulsed sources of radio waves, first observed in 1968. These objects, known every bit pulsars, emit very short bursts of radio waves separated in fourth dimension past intervals of the order of seconds.

This time interval between pulses is extremely stable, varying by less than x^-9s. Pulsars are believed to originate from rotating neutron stars, in which electrons trapped by the magnetic field feel large centripetal accelerations attributable to the rotation. The highly directional radio emissions sweep past the earth like a searchlight beacon equally the star rotates. Pulsars have been observed over the total range of the spectrum, including visible and 10-ray wavelengths.

5.Ultraviolet

The radiations of wavelengths shorter than the visible begin with the ultraviolet (1 nm to 400 nm), which tin exist produced in atomic transitions of the outer electrons every bit well as in radiation from thermal sources such as the sun.Because the outer atmosphere absorbs strongly at ultraviolet wavelengths, picayune of this radiation from the lord's day to the basis.

Nevertheless, the principal-agent of this assimilation is atmospheric ozone, which has been depleted in recent years as a upshot of chemical reactions with fluorocarbons released aerosol sprays, refrigeration equipment, and other sources. Cursory exposure to ultraviolet radiation causes mutual sunburn, but long-term exposure tin can atomic number 82 to more serious furnishings, including skin cancer. Ultraviolet astronomy is done using observatories carried into earth orbit by satellites.

6:X -rays

Ten -rays (typical wavelength 0.01 nm to 10 nm) tin can exist produced with discrete wavelengths in individual transitions among the inner (about tightly bound) electrons of an atom, and they tin also be produced when charged particles (such as electrons ) are decelerated. X-ray wavelengths represent roughly to the spacing betwixt the atoms of solids; therefore handful of x rays from materials is a useful way of studying their structure.

X-rays can easily penetrate soft tissue merely are stopped past bone and other solid matter, for this reason, they have constitute wide use in medical diagnosis. X-ray astronomy, like ultraviolet astronomy, is done with orbiting observatories. Most stars, such as the sun, are not strong ten-ray emitters; still, in certain systems consisting of 2 nearby stars orbiting almost their common center of mass (called a binary system), cloth from ane star can be heated and accelerated as it falls into the other, emitting x rays in the process. Although confirming evidence is not notwithstanding available, information technology is believed that the more than massive member of certain 10-ray binaries may be a black hole.

vii:Gama rays

Gamma rays are electromagnetic radiation with the shortest wavelengths (less than 10 pm). They are the most penetrating of electromagnetic radiations, and exposure to intense gamma radiation can have a harmful event on the human torso. These radiations tin can be emitted in transitions of an atomic nucleus from one state to another and can likewise occur in the decays of certain unproblematic particles; for example, a neutral pion can decay into two gamma rays according to π^°→ γ + ϒ and an electron and a positron ( the antiparticle of the electron) can mutually demolish into two gamma rays: e^–+ east⁺→ γ + γ In general, each such process emits gamma rays of a unique wavelength.In gamma-ray astronomy detection of such radiation (and measurement of their wavelength) serves as evidence of item nuclear processes in the universe.
