Answer: Ultraviolet rays are the wave which has high enough energy to cause damage to skin and sometimes cancer.
Step-by-step explanation:
Ultraviolet rays also known as UV rays have a range of wavelength from 400 nm to 10 nm.
As energy is inversely proportional to wavelength. Hence, shorter is the wavelength of a UV-ray higher will be its energy.
Also, UV rays have high enough energy due to which they are able to penetrate through the living cells causing damage to the skin. If a person remains under UV rays for a longer period of time then it can cause sunburn and could also cause skin cancer.
Thus, we can conclude that ultraviolet rays are the wave which has high enough energy to cause damage to skin and sometimes cancer.
