IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / â¦ 2). 6 people found this useful. Al Cohen.
Based on this equation, the energy of an electromagnetic wave is directly proportional to its frequency and inversely proportional to the wavelength. Thus, as frequency increases (with a corresponding decrease in wavelength), the electromagnetic wave energy increases, and vice versa.n order to operate the tutorial, first choose an exciting wavelength by using the mouse cursor to translate the Wavelength (or Energy) slider to the desired position. Next, use the mouse to press the blue Pulse button, which will excite the atom by absorption of a photon of the chosen wavelength.
