Ultraviolet rays

Explanation:

Frequency of a wave is equivalent to oscillations per second or vibrations per second. We know that frequency of gamma rays is maximum while the frequency of radio wave is minimum.

In this question, we have to write the type of electromagnetic wave just higher than visible light.

The frequency of visible light is in between 430 THz to 770 Thz where 1 THz = 10¹² Hz

The frequency of ultraviolet rays is in between to  . So,

Hence, the correct option is (E) " ultraviolet rays ".
