If a wave is traveling at a constant speed and the frequency is changed from 4 Hz to 2 Hz, how will the wavelength change?
The wavelength would produce a standing wave.
The wavelength will be halved.
The wavelength will remain unchanged.
The wavelength will double.
The wavelength will double.
Since the speed of the wave is constant and given by the equation speed = frequency x wavelength, if the frequency is halved, the wavelength must double in order to keep the speed constant.
