Gamma rays are known for being part of which type of spectrum?

Gamma rays are a type of electromagnetic radiation, which means they are part of the electromagnetic spectrum. The electromagnetic spectrum encompasses all types of radiation, arranged according to their wavelengths, from radio waves, through microwaves, infrared, visible light, ultraviolet, X-rays, and finally, gamma rays, which have the shortest wavelengths and the highest energy. In comparison, the visible spectrum contains only the light that is visible to the human eye, and it does not include gamma rays. The sound spectrum pertains to sound waves and is not related to electromagnetic radiation at all. The infrared spectrum is also just one part of the broader electromagnetic spectrum, specifically dealing with wavelengths longer than visible light and shorter than microwaves. Therefore, gamma rays belong to the electromagnetic spectrum, making the second answer the correct choice.
