A slab of a material of refractive index...


A slab of a material of refractive index 2 shown in fig. has a curved surface APB of radius of curvature 10 cm and a plane surface CD. On the left of APB is air and on the right CD is water with refractive indices as given in the figure. An object O is placed at a distance of 15 cm from the pole P as shown. The distance of the final image of O from P, as viewed from the left is......

Text Solution

Verified by Experts

For refraction at APB,
`-(mu_(2))/(u)+(mu_(1))/(upsilon)=(mu_(1)-mu_(2))/(R)`
`rArr(-2)/(-15)+(1)/(upsilon)=(1-2)/(-10)rArrv^(')=-30cm`
`rArr` The image `O^(')` will be formed at 30cm to the right at P.
