Question

Name the rays or waves of highest frequency.

• A. X-rays
• B. UV rays
• C. IR rays
• D. Gamma rays

Answer 1

The correct option is D Gamma rays

The electromagnetic spectrum in order of increasing frequency is - radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
The frequency of the gamma rays is ${>3\times 10}^{19}m$.
Hence, the gamma rays has the maximum frequency in the electromagnetic spectrum.
