Question

Explain electromagnetic radiations with the concept of wavelength?

Answer 1

Hint: If the wavelength of the electromagnetic series is in increasing order then the same electromagnetic radiations the frequency will be in decreasing order. The order of electromagnetic radiations is Radio waves > Microwaves > Infrared > Visible > Ultraviolet rays > X-rays > $\gamma $ -rays > Cosmic rays, in decreasing order of frequency.

Complete step-by-step answer:Electromagnetic waves are the waves having both electric and magnetic fields and both the fields are perpendicular to each other. There are many types of electromagnetic radiation like radio waves, UV-rays, X-rays, etc. They only differ by either wavelength or by frequency.
If the wavelength of the electromagnetic series is in increasing order then the same electromagnetic radiations the frequency will be in decreasing order. The order of electromagnetic radiations is Radio waves > Microwaves > Infrared > Visible > Ultraviolet rays > X-rays > $\gamma $ -rays > Cosmic rays, in decreasing order of frequency.
So, the order of electromagnetic radiations in the increasing order of wavelength will be:
Cosmic rays < $\gamma $ -rays < X-rays < Ultraviolet rays < Visible < Infrared < Microwaves < Radio waves.
The range of cosmic rays is ${{10}^{-17}}-{{10}^{-15}}m$
The range of $\gamma $ -rays is ${{10}^{-14}}-{{10}^{-12}}m$
The range of X-rays is ${{10}^{-12}}-{{10}^{-10}}m$
The range of Ultraviolet is ${{10}^{-10}}-{{10}^{-7}}m$
The range of visible is ${{10}^{-7}}-{{10}^{-5}}m$
The range of Infrared is ${{10}^{-5}}-{{10}^{-1}}m$
The range of Microwaves is ${{10}^{-1}}-{{10}^{1}}m$
The range of Radio Waves is ${{10}^{2}}-{{10}^{2}}m$

Note: The frequency is the number of waves passing and area in one second and wavelength is the distance between two consecutive crests or the distance between two consecutive troughs.
