A water wave undergoes diffraction as it goes through the gap between two barriers in a ripple tank. As it travels through the gap, the wave is seen to ‘spread out’. Which two factors both influence the amount of diffraction seen?
- Athe amplitude and frequency of the incident wave
- Bthe amplitude of the incident wave and the width of the gap
- Cthe wavelength and amplitude of the incident wave
- Dthe wavelength of the incident wave and the width of the gap
