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.
The second wave has twice the frequency of the first. You can see that the wavelength is halved when the frequency is doubled. The frequency #f# and wavelength #Î»# are related to one another and to the speed of the wave #v# by the formula. #fÎ» = v#. Since #v# is constant, if #f# increases, #Î»# must decrease, and vice versa.
