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.
Sep 21, 2015. If the speed of wave propagation remains constant, an increase in the wavelength will result in a decrease in the frequency. To see this relationship more clearly consider the situation where. the frequency (#f#) is in cycles/second. the wavelength (#lambda#) is in meters/cycle.
