Which of the following statements correctly describes the relation between frequency, wavelength energy and velocity of a wave t
Sedbober [7]

The statement that correctly describes the relation in the question is ; ( A ) As wavelength decreases, frequency increases, energy increases and the speed remains the same.

The Frequency of a wave travelling in a medium is directly proportional to the energy produced by the wave and inversely proportional to the wavelength of the wave.  

Changes in the wavelength and frequency of a wave has no effect on the wave speed. but has an effect on the energy produced by the wave. therefore the wave speed remains constant regardless of the changes in wavelength and frequency

Hence we can conclude that   As wavelength decreases, frequency increases, energy increases and the speed remains the same.
