3) Which one statement below is not a proper definition for the wavelength of a wave? A. The wavelength is the distance between successive crests for a wave. B. The wavelength is the speed of the wave multiplied by the period. C. The wavelength is the speed of the wave divided by the frequency. D. The wavelength is the distance between a trough and the next crest for a wave.

 

b. The wavelength is the speed of the wave divided by the period.

Wavelength is the distance between two successive crests or troughs of a wave. The wavelength is measured in the direction of the wave and this implies that the lower the frequency the longer the wavelength and in the same manner shorter the wavelength then this implies the higher the frequency. It is also the length of one complete wave cycle. Wavelength is the speed divided by the wave frequency and wavelength is measured in hertz or number of waves per second.
