What is an incident ray?

Academic Physics NCERT Class 8

An incident ray is a ray of light that strikes a surface. The angle between this ray and the perpendicular or normal to the surface is the angle of incidence.

The incident ray, the normal and the reflected ray lie in the same plane.

This is one of the laws of reflection.

Another law of reflection states that the angle of incidence and the angle of reflection are equal.

What is the angle of incidence of a ray if the reflected ray is at an angle of $90^{\circ}$ to the incident ray?
The angle between an incident ray and the plane mirror is 30°. The total angle between the incident ray and reflected ray will be:(a) 30° (b) 60° (c) 90° (d) 120°
In an experiment to trace the path of a ray of light through a glass prism for different values of angle of incidence a student would find that the emergent ray:(a) is parallel to the incident ray.(b) perpendicular to the incident ray.(c) is parallel to the refracted ray.(d) bends at an angle to the direction of the incident ray.
Explain a clear diagram of the incident ray and reflected ray.
Is the incident ray will be parallel to the emergent ray in a glass prism?
A ray of light is incident on a plane mirror at an angle of 30°. What is the angle of reflection?
A student traces the path of a ray of light through a triangular glass prism for different values of angle of incidence. On analyzing the ray diagrams, which one of the following conclusions is he likely to draw?(A) The emergent ray is parallel to the incident ray.(B) The emergent ray bends at an angle to the direction of the incident ray.(C) The emergent ray and the refracted ray are at right angles to each other.(D) The emergent ray is perpendicular to the incident ray.
Is diffuse and regular reflection follow the first law of reflection that is (the incident ray, the normal at the point of the incident, and the reflected ray all lie in the same plane)?
Describe an activity to show that the incident ray, the reflected ray and the normal at the point of incidence lie in the same plane.

What is a ray?
What is UV Ray?
What is Ray Box?
A ray of light is incident normally on a plane mirror. What will be the:(a) angle of incidence?(b) angle of reflection?
Two mirrors meet at right angles. A ray of light is incident on one at an angle of $30^{\circ}$ as shown in Fig. 16.19. Draw the reflected ray from the second mirror."
