When a glass slab is placed on a dot on a paper.It apperas displaced by`4`cm viewed normally.What is the thickness of slab if the refractive index`1.5`.

A bubble in glass slab (=1.5) when viewed from one side appears at 5 cm and 2 cm from other side, then thickness of slab is:

The critical angle of incidence in a glass slab placed in air is 45^@ . What will be be the critical angle when the glass slab is immersed in water of refractive index 1.33 ?

A glass slab of thickness 8 cms contains the same number of waves as 10 cms long path of water when both are traversed by the same monochromatic light. If the refractive index of water is 4/3, the refractive index of glass is
