# 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? - Science

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.

#### Solution

(B) The emergent ray bends at an angle to the direction of the incident ray.

In refraction of light through a glass prism, there is deviation or change in the path of light passing through the prism.
