2. A 50-cm tall fish tank is 3/4 full with oil and exposed to the air. A laser beam with a wavelength of 6333 Å (633.3 nm) is incident on the surface of the oil at an angle of 20° above the surface. (a) How far does the laser beam travel in the oil? (b) How long after striking the surface of the oil does it take for the laser beam to reach the bottom of the tank? Note- the index of refraction for the oil is 1.48. [Answer: (a) d = 0.49 m; (b) At = 2.4 × 10-9 s]
