Explain how the formation of a rainbow occurs.
State the dependence of angle of deviation on the refractive index of the material of the prism.
Which colour of light travels fastest in any medium except air?
Name a prism required for obtaining a spectrum of Ultraviolet light.
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?
The refractive index of glass is 1.5. From a point P inside a glass block, draw rays PA, PB and PC incident on the glass air surface at an angle of incidence 30°, 42° and 60° respectively.
- In the diagram show the approximate direction of these rays as they emerge out of the block.
- What is the angle of refraction for the ray PB?
`("Take" sin 42° =2/3)`
What should be the ratio of the speed of light through the liquid to the speed through the glass so that there is no refraction of light at the boundaries of the glass block when the system is illuminated by the light of one colour?
Comment on the statement ‘The refractive index of glass is 3/2.’
Draw ray of light bending towards the normal while passing from air to glass. Label your diagrams.
