Question

State and explain the laws of reflection of light at a plane surface with the help of labeled ray diagrams. Mark angle of ‘incidence’ and ‘reflection’ clearly on the diagram. If the angle of reflection is 47.5 , what will be the angle of incidence?
​

Answer 1

Laws of reflection

1. The incident ray, the reflected ray and the normal lie on the same plane.
2. The angle of incidence is equal to the angle of reflection.

If the angle of incidence is 47.5°, angle of reflection is also 47.5°
