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.
All electromagnetic waves move at the speed of light; subsequently, the wavelength and frequency of waves must be proportional, as the wavelength multiplied by the frequency equals the speed of light. As wavelength increases, frequency decreases, and as wavelength decreases, frequency increases proportionally. Keep Learning.
