Above is an applet that
illustrates Snell's law using Fermat's principle (least time). It shows many paths possible and the actual path is the one that
minimizes the time as the path that gets to the end point first is the actual
path that the light takes. Note that the non-correct paths take longer
times than the correct path.
Here is the question for Wednesday:
- The textbook definition of an inertial frame of reference is "a frame in which Newton's laws are valid." Practically speaking, how would you go about testing whether or not a given frame of reference constitutes an
inertial frame? (I will start you out easy...)
Answer in the form below, a short answer for each is fine.
