1. A blue laser of wavelength 460 nm in air enters a diamond having a high index of refraction of 2.4. What is the wavelength of this light after it enters the diamond?
2. A flagpole of total height 3.0 m sits in a pool of water that is 2.0 m deep. The sunlight hits the top of the flagpole at an angle θ = 30° above the horizon. Calculate the total shadow length on the bottom of the pool.
3. A laser pointer is held underwater in a pool that is 2.5 m deep. You wish to demonstrate total internal reflection. At what minimum distance from the edge of the pool (x) must I point the laser pointer to get Total Internal Reflection?
[Notes:
1. Answer precision should be to 0.1, i.e. 1.1 or 15.4.
2. You must provide correct units for full credit]
4. A triangular glass block has an index of refraction of 1.5. A red laser pointer enters the glass perpendicular to side A. Calculate the transmission angle as the light exits side C.
5. On the first day of Summer in Murfreesboro, TN the Sun reaches a maximum altitude of 77.5°. This sunlight is incident on a calm pool of water.
a. What is the angle of incidence of the Sun's light on the water's surface?
b. At what angle is the light refracted into the water?
c. What is the speed of light in the water? [Part C answers are scientific notation; for example, for 1.4 x 108 enter 1.4E8 as your answer.]
d. What are the correct units for the answer in Part C?
