Question

A hollow glass gives

Answer 1

Hint: In order to the question, to know that a hollow glass prism giving after the refraction, we should go through the mechanism and the principles of hollow glass prism and then we will also discuss, what happened when a beam of white light is incident on a hollow glass prism.

Complete step-by-step solution:
A hollow glass prism does not give any spectrum because this simple deviation of light takes place parallel to the incident ray like in a glass slab.

In cases other than glass, a hollow prism can be used to determine the angle of minimum deviation. In simple terms, a hollow prism is a prism that can be filled with a medium such as kerosene or spirit to take readings with minimum deviation. When mediums other than glass must be used, these prisms are used.

When mediums other than glass must be used, these prisms are used.
Principle of glass prism: Refraction of light through a prism at minimal deviation is used to assess the refractive indices of liquids and glass. A glass prism is a transparent structure with two plane surfaces that are inclined to each other.

Note: Now, we can ask a question: what happens when a beam of white light is incident on a hollow prism of glass? So, the light that emerges from the prism produces a rainbow, but all of the colours bend away from the centre. The light that emerges from the prism creates a spectrum, in which all colours bend towards the base, with violet being the most intense and red being the least intense.
