Refraction of Light Through a Glass Prism

Study the diagram carefully and answer the question that follow.

Give an example of the phenomenon occurring in (i) daily life, (ii) nature.

Study the diagram carefully and answer the question that follow.

Explain a method to recombine the separated colours to get back white light.

Study the diagram carefully and answer the question that follow.

Name the colour which deviates the (i) most (ii) least.

Study the diagram carefully and answer the question that follow:

Name the phenomenon involved.
(Reflection/Dispersion)

Study the diagram carefully and answer the question that follow.

Complete the above diagram indicating the names of the emerging colours in correct sequences.

Define dispersion. How is it caused? List its uses. Draw a diagram to show dispersion through a glass prism.

Describe an activity to show that white light is composed of seven colours and cannot be splitted further.

Explain the formation of rainbow in the sky. Draw diagram also.

What is meant by spectrum? Name all colours of a rainbow.

A glass prism produces a spectrum when white light passes through it but glass slab does not produce any spectrum. Explain why.

Why do different colours get separated when white light passes through prism? How can we recombine the components of white light after a prism has separated them? Explain with the help of a figure.

How will you use two identical prisms so that a narrow beam of white light incident on one prism emerges out of second prism as white light? Draw the diagram.

Name the component of white light that deviates (i) the least and (ii) the most while passing through glass prism.

Light of two colours $A$ and $B$ passes through a glass prism. ‘$A$’ deviates more than ‘$B$’ from its path of incidence. Which colour has higher speed in the prism?

Give one example of atmospheric dispersion of light.

Draw a diagram to show refraction of light through a glass prism. Mark Angle of deviation also.
