Answer:
Ultraviolet radiations are the waves that are produced from the surfaces that have an extremely high temperature. For example, the sun. It is comprised of a wavelength that ranges from 10 nm up to about 400 nm. The sun releases this UV radiation that gives about 10% of the total electromagnetic radiation.
These radiations are harmful to humans and organisms, which can cause various types of skin diseases. But it also provides vitamin D.
These radiations are divided into 3 types, and they are-
(a) Ultraviolet radiation A
(b) Ultraviolet radiation B
(c) Ultraviolet radiation C.
Hence, the letter C represents the UV radiation in the figure.
