**1. A light source, S, is located 2.0 m below the surface of a swimming**

pool and 1.5 m from one edged of the pool. The pool is filled to the

top with water.

a) At what angle does the light reaching the edge of the pool leave the

water?

b) Does this cause the light viewed from this angle to appear deeper or

shallower than it actually is?

**2. n**

_{i}*sinΘ_{i}= n_{r}*sinΘ_{r}**3. I have no idea how to do this problem.**

**1. A ray of light is incident upon a 600-600-600 glass prism, n=1.5.**

the angle od incidence is 45 degree.

a) Using Snell's law, determine the angle Θr to the nearest degree.

b) Using elementary geometry, determine the values of angles A, B,

and C.

c) Determine angle of refraction.

**2. n**

_{i}*sinΘ_{i}= n_{r}*sinΘ_{r}**3. a. n**

= sinΘ

= 1sin60/1.5

= 35.3 degrees

b./c. I have no clue. I know its suppose to be simple geometry but I can't seem to figure it out. :/

_{i}*sinΘ_{i}= n_{r}*sinΘ_{r}= sinΘ

_{r}= n_{i}sinΘ_{r}/n_{r}= 1sin60/1.5

= 35.3 degrees

**1. A sheet of plastic, n = 1.500, 25 mm thick is used in a bank teller's window. A ray of light strikes the sheet at an angle of 45 degrees. The ray leaves the sheet at 45 degrees but at a different location. Use a ray diagram to find the distance between the ray that leaves and the one that would have left in the plastic were not there.**

**2. n**

_{i}*sinΘ_{i}= n_{r}*sinΘ_{r}**3. How would you draw the ray diagram? I don't know if I need to use the 25 mm if so why and how?**

Thank YOU!! ;)
