A ray of light is incident on a plane mirror at an angle of 30°. What is the angle of reflection?

Academic Physics NCERT Class 10

The angle of reflection is 30°, as according to the law of reflection, the angle of incidence is equal to the angle of reflection.

A ray of light strikes a plane mirror at an angle of 40° to the mirror surface. What will be the angle of reflection?
A ray of light is incident on a plane mirror making an angle of 90° with the mirror surface. The angle of reflection for this ray of light will be:(a) 45° (b) 90° (c) 0° (d) 60°
A ray of light falls on a plane mirror forming an angle of 20 degree with the mirror. The deviation of the rayâ€‹ on reflection is?
A ray of light strikes a plane mirror such that its angle of incidence is 30°. What angle does the reflected ray make with the mirror surface?
A ray of light strikes a plane mirror PQ at an angle of incidence of 30°, is reflected from the plane mirror and then strikes a second plane mirror QR placed at right angles to the first mirror. The angle of reflection at the second mirror is:(a) 30° (b) 45° (c) 60° (d) 90°Draw a ray-diagram to illustrate your answer.
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°
What is the angle of incidence of a ray if the reflected ray is at an angle of $90^{\circ}$ to the incident ray?
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."
Draw a ray diagram to show the path of the reflected ray corresponding to an incident ray of light parallel to the principal axis of a convex mirror and show the angle of incidence and angle of reflection on it.
Draw a labelled ray diagram to show the path of the reflected ray corresponding to an incident ray of light parallel to the principal axis of a convex mirror. Mark the angle of incidence and angle of reflection on it.
State and explain the laws of reflection of light at a plane surface (like a plane mirror), With the help of a labelled ray-diagram. Mark the angles of 'incidence' and 'reflection' clearly on the diagram. If the angle of reflection is 47.5°, what will be the angle of incidence?
How is the reflection of light ray from a plane mirror different from the refraction of light ray as it enters a block of glass?
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.
What is meant by the 'angle of incidence' and the 'angle of refraction' for a ray of light? Draw a labelled ray diagram to show the angle of incidence and the angle of refraction for a refracted ray of light.
