Which type of radiation has the highest frequency in the electromagnetic spectrum?

  1. Microwaves

  2. Visible light

  3. Gamma rays

  4. X-rays

The correct answer is: Gamma rays

Gamma rays have the highest frequency in the electromagnetic spectrum. This is because, in the electromagnetic spectrum, frequency increases as one moves from radio waves to microwaves to infrared, then to visible light, ultraviolet, X-rays, and finally to gamma rays. Gamma rays not only possess the highest frequency but also have the shortest wavelengths. The properties of gamma rays make them extremely high-energy radiation, capable of penetrating materials that lower frequency radiation cannot. This high energy and frequency are what distinguish gamma rays from the other types of radiation listed, such as X-rays, visible light, and microwaves, which all occupy lower frequency ranges within the spectrum.
