  1. An underwater laser light is at the bottom of a swimming pool, and is pointed towards the surface. A light ray from the laser makes an angle of incidence of ?i=350 at the surface of the water. [Note: ??????=1.33; ????=1.00]

  1. Calculate the angle of refraction of the laser light when it emerges into the air above the water. Determine the critical angle of incidence of the laser light to have Total Internal Reflection.

A silver coin sits on the bottom of a swimming pool that is 4 meters deep. A beam of light reflected from the coin emerges from the pool making an angle of 20 degrees with respect to the water’s surface and enters the eye of an observer. Extend this ray, which goes from the water-air surface to the eye, straight back until it intersects with the vertical line drawn through the coin. What is the apparent depth of the swimming...

A laser is aimed at the top of a pool of water. The beam makes an angle of 32 degrees to the normal to the water's surface. If the pool of water is 2.3 m deep with a flat bottom, where will the light beam hit the bottom of the pool relative to its entrance point on the air–water interface. Use nair = 1 and nwater = 1.33 for your calculations.
