Question

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.(All India - 2015)

Answer 1

Answer:

When a ray of light passes through any medium, it is bend either away from normal or towards the normal. So, when a path of ray of light passes through a triangular glass prism for different values of angle of incidence, then the emergent ray bends at an angle to the direction of the incident ray.
