Write a short note on dispersion of light.
Name one factor that affects the lateral displacement of light as it passes through a rectangular glass slab.
How does the angle of minimum deviation produces by a prism change with increase in :

The diagram alongside shows the refraction of a ray of light from air to a liquid.
- Write the values of (i) angle of incidence, (ii) angle of refraction.
- Use Snell’s law to find the refractive index of liquid with respect to air.

How does the deviation produced by a prism depend on the refraction index of its material.
Why upper surface of water contained in a beaker and above eye level appears silvery?
What is the total reflecting prism?
Explain with the help of a diagram of how fish is able to see the objects above it.
Consider these indices of refraction: glass: 1.52; air: 1.0003; water: 1.333. Based on the refractive indices of three materials, arrange the speed of light through them in decreasing order.
