Question
What is the angle between a reflected ray and normal?
- 90 degrees
- Angle of reflection
- Angle of incidence
- 180 degrees
Solution
The angle between a reflected ray and the normal is always equal to the angle of incidence, according to the law of reflection. This means that if a light ray hits a surface at a certain angle to the normal (the line perpendicular to the surface), it will reflect off the surface at the same angle to the normal.
However, if you're asking about the angle between the reflected ray and the surface (not the normal), it would be 180 degrees minus the angle of incidence.
The 90 degrees you mentioned is the angle between the surface and the normal, not between the reflected ray and the normal.
