A concave spherical surface of radius of curvature 100 cm separates two media of refractive indices 1.50 and `(4)/(3)`. An object is kept in the first medium at a distance of 30 cm from the surface. Calculate the position of the image.

Explanation

`mu_(1)=1.50,mu_(2)=4/3,u=-30cm,R=-100cm`
`mu_(2)/v-mu_(1)/u=(mu_(2)-mu_(1))/R`
`(4//3)/v-1.50/(-30cm)=(4/3-1.50)/(-100cm)`
`rArrv=-27.58cm`
