"rough surface"...rays are scattered in whatever direction the rough ridge indicated it should do.
I would go with D. The real issue is how "rough".
a ray of light strikes a rough surface such that the angle of incidence is 40.0. what is the angle of reflection
1. 0 degrees
2. 20.0 degrees
3. 40.0 degrees
4. the angle of reflection cannot be determined.
I am confused between 3 and 4 but I think the correct answer is 40.0 degress.
Can someone please confirm
Thanks
