Question about reflecting light off a mirror

[chambers.keivn]

Hello all,

I've got a question, obviously. I've got a light shining down from directly up above think laser, I want to reflect the light to hit the wall, redirect it 90 degrees. What angle would the mirror need to be to do this? For some reason I'm thinking 45 degrees.

Thanks,

You're right. :-)
This is the law of reflection.
