Which of the following electromagnetic radiations has the shortest wavelength in the electromagnetic spectrum?

💡 Solution & Explanation

Gamma rays possess the shortest wavelength and highest frequency in the electromagnetic spectrum, carrying the maximum energy per photon among all types of radiation. Other options like radio waves sit at the opposite end of the spectrum with the longest wavelengths and lowest energies. Gamma rays originate from radioactive atomic nuclei and certain astronomical phenomena like supernova explosions. Because of their high penetrating power, they are used in radiation therapy to treat cancer and sterilize medical equipment.
