Description: In the ripple tank below. Three acryllic pieces were placed in the water in order to create a barrier with two small openings. The play rate is 15 frames per second. Larger Video Frame Questions: 1. Compare the frequency and wavelength of the waves emerging from the upper opening to the waves emerging from the lower opening. 2. Are there any anti-node lines visible? State how many and (roughly) where they are. 2. How is this clip similar to the previous three clips? 3. How is this clip different from the previous three clips? 4. If the openings were made larger what changes would happen to the pattern? State observational evidence in defending your answer. 5. If the openings were placed further apart, what changes would happen to the pattern? Again, use your observations to form an answer.
