Write a Report on how Ripple Tank is used to explain the following: A. Interference pattern for two point sources - varying distance between the sources and frequency (note that frequency can be varied independently for the two sources) B. Refraction for plane waves travelling from deeper water into a submerged block. C. Refraction for plane waves travelling from the submerged block to deeper water. D. Diffraction for an opening smaller than the wavelength. E. Diffraction for an opening larger than the wavelength. 1. Write out a purpose for each scenario and develop a method to test your purpose using the materials at your disposal. 2. Make an hypothesis - this could be a description or a sketch of the wave pattern you think you'll see. 3. Explain each concept and how it relates to the wave theory of light. Include diagrams with labels. 4. Compare your hypotheses to your results, discuss, and answer any related analysis questions. 5. Summarize your conclusions. Include errors improvements and further studies. Analysis Questions: A1. How does the distance between the sources affect the interference pattern? A2. How does the frequency affect the interference pattern? A3. How does the interference pattern change if the frequencies of the two point sources are different? B1. What happens to the wavelength of plane waves when they go from deeper water to the submerged block? B2. The frequency of water waves in this scenario is constant. Based on the change in wavelength, are the waves speeding up or slowing down? Is the change in speed consistent with the change in wave direction? What happens to the wavelength of plane waves when they go from the submerged block to deeper water? C2. The frequency of water waves in this scenario is constant. Based on the change in wavelength, are the waves speeding up or slowing down? C3. Is the change in speed consistent with the change in wave direction
