Glass is optically .................. (denser/rarer) than water.

When the speed of light slows down in a medium, that medium is said to be optically ...................... (rarer/denser).

Kerosene is denser than water.

Water is optically rarer than .......

Solids which are denser than a liquid ................ (float/sink) in that liquid.

Water glass is :

A light ray in passing from medium A to medium B slows down. (i) Draw a diagram to show the path of the light ray in the two media. (ii) Name the medium which is optically denser than the other.

Diamond is optically denser than glass and water.

A ray of light travels from an optically denser to rarer medium. The critical angle of the two media is C. The maximum possible deviation of the ray will be

Observe the given figure and identify which medium is optically denser and which is optically rarer.

When a ray of light travels from optically denser medium to optically rarer medium, it always bends towards the normal.
