Explanation:

X rays carry the maximum energy per photon. Hence, it has high penetrability. Thus it is used in diagnostic centres for imaging our bones and teeth.

So, if you increase the frequency of the wave, you get more energy per photon. High frequency Gamma rays photons have maximum energy compared to other photons in the electromagnetic spectrum. It is followed by X-rays, UV rays, Light waves, Infrared, Microwaves and Radio waves.
