If a light ray is impingent on a smooth surface at an angle of 1.90E+1 deg to the normal, what will be its angle of reflection?
Added by Margaret P.
Step 1
The law of reflection states that when a light ray reflects off a smooth surface, the angle of incidence (the angle between the incident ray and the normal to the surface) is equal to the angle of reflection (the angle between the reflected ray and the normal). Show more…
