Suppose you are standing on the shore of a freshwater lake with a laser pointer with a wavelength of 589 nm. a. What is the frequency of your laser pointer when you shine it on the ground? b. You shine the laser pointer down to an observer who is motionless 1.0 m below the surface of the lake. If you shine the light at an angle of 60° incident to the surface of the lake, what angle of refraction does the underwater observer see relative to the surface of the water? c. What frequency and wavelength does the laser pointer have for the underwater observer? (The underwater observer is not wearing goggles.) d. You see someone on a very fast train moving away from you at 150 m/s. You shine the laser pointer at this person. What frequency do they measure for the light? What wavelength? e. How fast would the train have to be moving for the person on the train to observe the same wavelength as the person underwater? How does this speed compare to the speed of light? Is it possible for a train to move this fast? Suppose you are standing on the shore of a freshwater lake with a laser pointer with a wavelength of 589 nm. a.
