Ripple Tank Research Report Complete the following questions . Write a Report on how Ripple Tank is used to explain the following: 1. HWPP'N Interference pattern for two point sources - varying distance between the sources and frequency (note that frequency can be varied independently for the two sources). Refraction for plane waves travelling from deeper water into a submerged block. Refraction for plane waves travelling from the submerged block to deeper water. Diffraction for an opening smaller than the wavelength. Diffraction for an opening larger than the wavelength. Write out a purpose for each scenario and develop a method to test your purpose using the materials at your disposal. Make an hypothesis - this could be a description or a sketch of the wave pattern you think you'll see. Explain each concept and how it relates to the wave theory of light. Include diagrams with labels. Compare your hypotheses to your results, discuss, and answer any related analysis questions. Summarize your conclusions. Include errors improvements and further studies
