Question

g Consider four different types of electromagnetic radiation: radio waves, infrared, ultraviolet, and gamma rays. Arrange the types of radiation from the shortest to the longest wavelength, and from the lowest to the highest energy.

Answer 1

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.

$E=\frac{hc}{\lambda}$

where,

E = energy of the wave

c = speed of light  

$\lambda$  = 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.
