Answer: shortest to longest wavelength : gamma rays , ultraviolet, infrared and radio waves,
lowest to the highest energy : radio waves, infrared , ultraviolet and gamma rays
Explanation:
Electromagnetic wave is defined as the wave which is associated with both electrical and magnetic component associated with them. They can travel in vacuum as well and travel with the speed of light.
The electromagnetic radiations consist of radio waves, microwaves, infrared ,Visible , ultraviolet, X rays and gamma rays arranged in order of decreasing wavelengths.
where,
E = energy of the wave
c = speed of light
= wavelength of the wave
Thus as energy and wavelength are inversely related, the order of increasing energy is radio waves, microwaves, infrared ,Visible , ultraviolet, X rays and gamma rays.
