A Physics 1C student is testing a new type of plastic. He conducts an experiment to measure the critical angle of the light, as shown in the figure to the right. The student measures the critical angle to be 52.5°. He then repeats the experiment with the same setup except that the plastic is instead immersed in water (n = 1.33) instead of air. What critical angle does he measure with this second experiment? plastic air a. 48.6°. b. 52.5°. c. 62.7°. d. 41.8°. e. He does not find total internal reflection anymore.

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
