Question

*The incident ray, the reflected ray and the normal to the surface all lie on the same plane. This plane is known as ________________.*

1️⃣ angle of incidence
2️⃣ plane of incidence
3️⃣ plane of reflection
4️⃣ angle of reflection​

Answer 1

Answer:

Angle of incidence

Explanation:

In geometric optics, the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal. ... The angle of incidence at which light is first totally internally reflected is known as the critical angle.
