Draw a ray diagram to show the dispersion of white light.
- A ray of white light breaks up into its components while passing through a glass prism. Draw a ray diagram to show the path of rays.
- Mark the least deviated colour in your diagram.
- Why do different coloured rays deviate differently in a prism?
When a ray of light enters a prism, it bends ______ the normal; as it leaves the prism, it bends ______ the normal.
In the figure given alongside, a narrow beam of white light is shown to pass through a triangular glass prism. After passing through the prism, it produces a spectrum YX on the screen.
- State the colour seen
- at X, and
- at Y.
- Why do different colours of white light bend through different angles with respect to the incident beam of light?
What is a rainbow?
The colour of white light which is deviated the maximum on passing through the glass prism is:
(a) blue
(b) indigo
(c) red
(d) orange
How does the speed of light determine the optical density of a medium?

Which characteristic property of light is responsible for the blue colour of the sky?
State two uses of ultraviolet radiation.

Sunlight entering through a narrow aperture falls on a prism. Draw a neat labelled ray diagram to show the formation of the spectrum on a screen. Name the colour obtained nearer the base of the prism.
Which of the following is a natural phenomenon which is caused by the dispersion of sunlight in the sky?

A prism of refractive index `sqrt2` and refracting angle A produces minimum deviation δm of a ray on one face at an angle of incidence 45°, The values of A and δm are, respectively ______.
When sunlight passes through water droplets in the atmosphere it gets dispersed into its constituent colours forming a rainbow. A similar phenomenon is observed when white light passes through a prism.
Instead of sunlight, a green-coloured ray is passed through a glass prism. What will be the colour of the emergent ray?
