Which one of the following types of radiations has the smallest wavelength?

Options

  1. AMicrowaves
  2. BInfra-red
  3. CVisible light
  4. DX-rays

Correct answer

D. X-rays

Step-by-step solution

X- Rays have smaller wavelengths and therefore higher energy than ultraviolet waves. Microwaves are the highest frequency of radio waves. Their wavelength is only a few centimetres long. Infrared lies between the visible and microwave portions of the electromagnetic spectrum. Shorter, near infrared waves are not hot at all in fact you cannot even feel them. Visible waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the
