Consider the situation in figure. The bottom of the pot is a reflecting plane mirror, S is a small fish and T is a human eye. Refractive index of water is mu. (a) At what distance(s) from itself will the fish see the image(s) of the eye ? (b) At what distance(s) from itself will the eye see the image(s) of the fish. (11-T

Answer

A, B, C, D

Explanation

As shown in given ure
`(sin45^@)/(sinr)=2/1`
`rarr sinr=(sin45^&@)/(sinr)=1/(2sqrt2))`
`rarr r=21^@`
`:. theta =(45^@-21^0)`
`=24^@=0.406xxABsin24^@`
`(AE)/(cos21^@)xx0.406`
`=(1,41xx0.406)/0.93=0.63cm`
