What is true about the relationship among wavelength, frequency, and energy in electromagnetic radiation? Gamma rays have lower frequency, longer wavelength, and lower radiant energy than x-rays. Ultraviolet waves have lower frequency, longer wavelength, and lower radiant energy than radio waves. Infrared waves have lower frequency, longer wavelength, and lower radiant energy than microwaves. Television waves have lower frequency, longer wavelength, and lower radiant energy than visible light.
