Which type of radiation has the longest wavelengths and lowest energies?

Explanation:
Long wavelengths mean low energy per photon because energy = h × frequency, and frequency is inversely related to wavelength (frequency = c/λ). Among the options, radio waves and microwaves have the longest wavelengths, so their photons carry the least energy. Gamma rays have the shortest wavelengths and highest energy, while ultraviolet and visible lie between them. So radio waves and microwaves have the longest wavelengths and lowest energies.
