Question

The incident ray, the reflected ray and normal at the point of incidence lie in the______.
1. different media
2. different plane
3. same plane
4. same surface

Answer 1

Correct Answer - Option 3 : same plane

The correct answer is same plane.

• The incident ray, reflected ray, the refracted ray and the normal of the system lie in the same plane.

• The ray of light that hits the polished surface is called the incident ray.
• The ray that gets reflected away is called the reflected ray.
• The point at which the light hits the surface is called the point of incidence.
• If a line is drawn perpendicular to that point, it is called the normal.
