A laser beam is pointed so that it passes through side A of the triangular glass (n = 1.5) prism shown below at an angle of incidence of 0°. The ray then strikes the far side of the prism (the hypotenuse). This experiment is conducted first when the prism is surrounded by air (n = 1) and then when the prism is surrounded by water (n = 1.33). 60° Side A 30° Side B Instructions 1. Draw a sketch of the physical situation with all given physical quantities clearly labeled. Your sketch should include both when the prism is in air and when it is in water. If you are unsure of the path the light will follow after hitting the far side of the prism, do not include that in your sketch. 2. Draw a ray diagram which represents what happens to the light when it is incident on the hypotenuse of the prism (a) when the prism is in air and (b) when the prism is in water. Include both reflected and refracted rays in your ray diagram. 3. Determine whether the light from the laser will pass through the hypotenuse of the prism when (a) the prism is in air and (b) the prism is in water. If it will, determine the angle of refraction in each medium. Support your answer with a complete mathematical procedure and explain your thought process in words. 4. Evaluate your answer. Consider all aspects of your answer (the numerical value, sign, and units) in your evaluation.
