A beaker contains water up to a height `h_1 ` and K oil above water up to another height `h_2.` Find the apparent shift in the position of the bottom of the beaker when viewed from above. Refractive index of water is `mu_1` and that of K.oil is mu_2`.

A

`(1+(1)/(mu_(1)))h_(1)-(1+(1)/(mu_(2)))h_(2)`

B

`(1-(1)/(mu_(1)))h_(1)+(1-(1)/(mu_(2)))h_(2)`

C

`(1+(1)/(mu_(1)))h_(2)-(1+(1)/(mu_(2)))h_(1)`

D

`(1-(1)/(mu_(1)))h_(2)+(1-(1)/(mu_(2)))h_(1)`

Text Solution

The correct Answer is:
4
Total shift =shift in water +shift in kerosene
`=(1-(1)/(mu_(1)))h_(1)+(1-(1)/(mu_(2))) h_(2)`
