Q1. A rocket moves with a velocity of 0.818c to the right with respect to a stationary observer A. An observer B moving relative to observer A finds that the rocket is moving with a velocity of 0.922c to the left. What is the velocity of observer B relative to observer A?
Q2. A diver shines a light up to surface of a flat glass-bottomed boat at an angle of 36 relative to the normal. If the indices of refraction of air, water, and glass are 1.0, 1.33, and 1.5 respectively, at what angle does a light leave the glass (relative to its normal)?
