Explain electromagnetic radiations with the concept of wavelength?
Solution
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 > γ -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 > γ -rays > Cosmic rays, in decreasing order of frequency.
So, the order of electromagnetic radiations in the increasing order of wavelength will be:
Cosmic rays < γ -rays < X-rays < Ultraviolet rays < Visible < Infrared < Microwaves < Radio waves.
The range of cosmic rays is 10−17−10−15m
The range of γ -rays is 10−14−10−12m
The range of X-rays is 10−12−10−10m
The range of Ultraviolet is 10−10−10−7m
The range of visible is 10−7−10−5m
The range of Infrared is 10−5−10−1m
The range of Microwaves is 10−1−101m
The range of Radio Waves is 102−102m
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.
