What is the first law of reflection? The angle of incidence is equal to the angle of reflection. What is common between the incident ray, the normal and the reflected ray? They all lie on the same plane. And this is the second law of reflection. Watch this video to experience an introduction into the world of light.
The first law of Reflection states that the incident ray, the normal and the reflected ray lie in a same plane.
The second law of Reflection states that the angle of incidence (incoming ray) is equal
to the angle of reflection (outgoing ray). This law of reflection is applicable for both plane and non-plane mirrors.
If the reflecting surface is plane, the reflection of light which occurs is termed as a regular reflection. The laws of reflection are as follows:
1.The incident ray, the normal and the reflected ray at the point of the incidence lie in the same plane.
2. The angle formed by the incident ray with normal will be equal to the angle formed by the reflected ray.
3.Both reflected ray and the incident ray are on the opposite sides of the normal.
The common between the incident ray, the normal and the reflected ray are they are coplanar i.e. all three lies in a same plane.
