Question

in the electromagnetic spectrum, which type of radiation has less energy than visible light?
x rays
gamma rays
ultraviolet
microwaves

Explanation:

In the electromagnetic spectrum, energy of radiation is related to its frequency (or wavelength). The order of increasing energy (and frequency, decreasing wavelength) is: radio waves, microwaves, infrared, visible light, ultraviolet, X - rays, gamma rays. So we need to find which option has less energy than visible light. X - rays, gamma rays, and ultraviolet have higher energy than visible light. Microwaves have lower energy (longer wavelength, lower frequency) than visible light.

Answer:

D. microwaves
