Homework Help: Physics

Posted by Jordan on Friday, July 12, 2013 at 11:48am.

Which of the following is correct for the reflected ray if a light ray strikes a plane mirror at an angle of 50° from the normal?

a. 40° from the surface of the mirror

b. 40° from the normal

c. 50° from the surface of the mirror

d. 90° from the normal

I have been stuck on this question for a while and I think it is because I am not sure I truly understand the question so I am not entirely convinced that I know the correct answer. I think the answer is either 40 degrees from the normal or 90 degrees from the normal but I do not know for sure. If you could help me answer this question and explain it to me it would be greatly appreciated.
