Solution of Chapter 13. How light travels through a prism? (Science Lab Manual Book)

AIM

Tracing the path of the rays of light through a glass prism.

What is a prism?

What happens to oblique ray when it enters the prism?

What are the factors angle of deviation depends upon?

What is the angle of minimum deviation?

What will happen when white light passes through the prism?

Give the order of colour when the light gets dispersed by a prism?

Why do different colour emerges through a prism in a different direction?

Which colour will deviate maximum and minimum?

What will When we pass light through the combination of two inverted prisms placed together?

What is meant by an angle of the prism?

What is the angle of emergence?

If the emergent ray makes an angle of 40 with the second refracting surface of the prism ,then find the angle of emergence.

In the experiment to trace the path of a ray of light through a triangular prism,

1. A student is asked to draw the boundary of the prism , why?

2. If the angle of incidence is 30, what can be the measure of the angle of incidence at minimum deviation ?

In the experiment to trace the path of a ray light a triangular glass prism.

1. If the emergent ray makes an angle 35 with the second face of the prism , then what is the angle of emergence.

2. Can the angle of deviation be zero and why?

What is the property of the image formed by the prism?
