(c) frequency
(d) period
(e) none of these. Explain your choice.
Problems
1. A pool of water is 3.00 m deep and 4.00 m wide. Someone lying with his face close to the water is looking for a coin that is directly across the pool on the bottom far edge. Will he be able to see it?
2. A prism, ABC, is cut such tht angle BCA = 90 deg and angle CBA = 45 deg. What is the miniumum value of its index of refraction if, while immersed in air, a beam traversing face AC is to totally internally reflected from face BC?
