Which of the following has the shortest wavelength?

Gamma rays have the shortest wavelength among the electromagnetic spectrum options listed. Wavelength is inversely related to frequency; as wavelength decreases, frequency increases. Gamma rays have extremely high frequencies, which means they correspond to very short wavelengths. This characteristic allows gamma rays to carry a significant amount of energy, making them useful in medical treatments such as cancer radiation therapy, as well as in various applications in astrophysics and nuclear physics. In contrast, ultraviolet rays, X-rays, and infrared rays have longer wavelengths than gamma rays, placing them further along the spectrum toward longer wavelengths. Familiarity with the electromagnetic spectrum emphasizes the role of gamma rays as the highest energy form of electromagnetic radiation.
