A student enters Best Buy prepared to buy a pair of speakers. Before he does, he conducts an experiment with them. He places them 4.0 m apart and then connects a signal generator to both speakers that produces a single tone of 240 Hz. He then walks in front of the speakers so that he is 2.0 m from one speaker and 5.0 m from the other. If the speed of the sound in the room is 360 m/s, will he be standing in a "quiet" spot? Explain.

The water in the tank has an index of refraction of 1. 10, the film has an index of refraction of 1.21, and the glass has an index of refraction of 1.40. The film is 90. 0 nm thick and is such that the light reflecting back at the angler fish has been minimized. Find the wavelength of the angler fish's light. (5 marks) 3.
