33. Bruno is standing upon the edge of the water with his high-powered laser gun, waiting to zap the next visible fish with a burst of laser light. Frieda deFish, located a distance of 2.17 m out from shore, hopes to hide from view by ducking behind a small lily pad.

1. A ray of light is passing through air (n=1). It strikes a level surface of water (n=1.33) at an angle of 40° with respect to the surface of the water. The water is 10 cm thick. The light ray refracts and travels through the water. There is a level layer of clear polystyrene (n = 1.6) that the water is resting upon. The light ray hits the polystyrene level and travels through it, finally reaching a sheet of glass (n=1.45). Given that the speed of light in a vacuum is 3 x 108 m/s, calculate the speed of light in the water and the time it takes for the light to traverse the water layer. (actual question i need answered) *Using the arrangement in Problem 1, calculate the critical angle for total internal reflection at the polystyrene-glass interface
