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.
