I did some research behind it, and some sources are claiming that recent studies show light doesn't always travel at the speed proposed by Einstein's theory. However, for the purposes of this class the speed of light is assumed to be constant.

Would it be advisable to calculate using 2.99792 x 10^8 on the exams? I'm not sure when to apply significant figures - either throughout the problem or just for the final answer.

I am sure that we will get a cover sheet with all of the constants/equations as we did on the first test on all future tests as well.
