For which colour of white light, is the refractive index of a transparent medium the most?
Fig 4.31 below shows a light ray of single colour incident normally on two prisms A and B. In each case draw the path of the ray of light as it enters and emerges out of the prism. Mark the angle wherever necessary.
Observe the figure and write accurate conclusion regarding refraction of light.
A ray of light passes from water to air. How does the speed of light change?

Comment on the statement ‘The refractive index of glass is 3/2.’
The diagram shows the path of a ray of light through a rectangular glass block placed in a liquid of uniform density.
Show with the help of a ray diagram the path of the ray when incident ray normally falls on the first surface of the glass block and passes through the block and the liquid.
