उत्तर
Gamma rays
Explanation:
The electromagnetic spectrum is the dispersion of electromagnetic radiation based on energy. Gamma rays, x-rays, ultraviolet, visible, infrared, microwaves, and radio waves are the seven main categories that it falls under. These zones are given in decreasing energy and frequency and rising wavelength order. Among the main types of electromagnetic radiation, gamma waves have the highest frequencies (most energetic) and shortest wavelengths, whereas radio waves have the lowest frequencies (least energetic) and longest wavelengths. Therefore, the smallest wavelength is that of gamma rays.
