A ripple tank and a barrier containing one narrow opening are set up to show the diffraction of water surface ripples. At first, the wavelength of the ripples is five times smaller than the width of the gap in the barrier. Which change would make the diffraction more pronounced?
- Adouble the amplitude of the ripples
- Bdouble the width of the gap
- Chalve the frequency of the ripples
- Dhalve the wavelength of the ripples
