Question

Which of the following types of radiation is nonionizing and has the shortest wavelength?
A) ultraviolet light
B) infrared radiation
C) microwaves
D) X rays
E) gamma rays

Accepted Answer

Nonionizing radiation does not have enough energy to remove electrons from atoms or molecules, and ultraviolet light falls under this category. It has a shorter wavelength than infrared radiation, microwaves, and radio waves, but is longer than X-rays and gamma rays, which are both ionizing radiations.
