Question

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.

Answer 1

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