The wavelength of the light is the ratio of the product of Planck's constant and the speed of light in a vacuum to the energy carried by the light. The unit of wavelength is the same as the unit of length which is meter.Answer and Explanation: We are given the followi...
Radio waves are electromagnetic waves whose wavelength is more than the infrared rays. Therefore, the frequency of the radio waves is less than that of the infra-red rays. Wave Travel:The wavelength of a wave, λ (m), is the distance the wave travels ...
