Define refraction and state the laws of refraction.


How is the reflection of light ray from a plane mirror different from the refraction of light ray as it enters a block of glass?

An object is viewed through a glass prism with its vertex pointing upwards. It appears to be displaced upward. Explain the reason. 


Name the factors on which the deviation produced by a prism depends.

Draw ray of light bending towards the normal while passing from glass to water. Label your diagrams.


After a robbery, if a window has been broken, there will be tiny particles of glass. Some of these will be found at the scene of the crime and some may be caught in the thief’s clothing. If the police can prove that these particles are identical, they have a strong case.
A method of doing this is to suspend the particles of glass in a special liquid. Light of a single colour is thrown through the liquid and the particles viewed through a microscope. The temperature of the liquid is then slowly altered. This alters the speed of light through the liquid (i.e., it alters the refractive index). At one particular temperature, the particles of glass disappear. It this happens at the same temperature for both sets of glass particles, they probably came from the same broken pane of glass.
Complete and copy the diagram to show how light bends when it travels from the liquid to the glass and back to the liquid, If the light slows down in the glass.


The diagram shows the path of a ray of light through a rectangular glass block placed in a liquid of uniform density.

What is the angular, deviation of the emergent ray from the glass block with respect to the incident ray?


Trace a ray of light incident at 30° on a surface if travelling from air to glass. What is the angle of refraction in this case? (R.I. for glass = 3/2).


The velocity of light in diamond is 121000 kms-1. What is its refractive index?
