Question

Nature of the water drop present in the glass slab with refractive index of water is 1.33 and refractive index of glass is 1.5

Answer 1

Nature of the water drop present in the glass slab is  of a magnifying lens.

Given,

refractive index of water =  1.33 and

refractive index of glass = 1.5 .

For a light ray coming from the bottom of the glass ,

• It bends towards the normal , since refractive index of glass is more than that of air.

Now this light ray passes to water.

• Its given that refractive index of water is less than that of glass.
• Hence the light ray will bend away from the normal.

After this the light ray passes to the air medium.

• Since refractive index of air is less than that of water, it bends away from the normal.
• Hence the light ray gets deviated by a large amount.
• Hence the object will appear big to an observer on top of the glass slap.
