Problem 7: If the new frequency of an electromagnetic wave is two-thirds of its old frequency, then what will be the new wavelength of the wave? As the wavelength of the radiations decreases, the frequency of the wave escalates. See the attached image below :). Since all that waves really are is traveling energy, the more energy in a wave, the higher its frequency. This basically means that when the wavelength is increased, the frequency decreases and vice versa. increasing frequency. unit of wave velocity is ms. Students might also compare the size of the wavelength of various waves to the sizes of common objects, as illustrated in the above figure. Students should also note the linear, correlated relationship between frequency and energy: as frequency increases, energy increases.
