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.

1 answer

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.
