The dipper moves up and down with a frequency of 40HZ . Determine the wavelength of the wave in cm.

Wavelength is defined as distance between successive crests or troughs. Based on tbe given diagram, there are 4 spacings between two successive crests. Given fiagram shows 5 spacings across the 10 cm. Hence   wavelength = ( 10 / 5 ) 4. Hopefully, my explanation is able to allow u to understand the answer.
