Question

which wave has highest and lowest wavelength

Answer 1

violet has the highest frequencyand the shortest wavelength of the visible colors of light. And red has the lowest frequency and the longest wavelength of the visible colors of light.

Answer 2

Radio waves, on the other hand, have the lowestenergies, longest wavelengths, and lowestfrequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.
