There is a small pin on a table. The pin is viewed from 50 cm above it. Now without disturbing the pin, a glass slab of 15 cm thickness is held above the pin, parallel to the table top. If the refractive index of glass is 1.5 , calculate the height (in cm) at which (from the pin) the image of the pin is formed.

A small pin fixed on a table top is viewed from above from a distance of 50cm. By what distance would the pin appear to be raised if it is viewed from the same point through a 15cm thick glass slab held parallel to the table? Refractive index of glass = 1.5. Does the answer depend on the location of the slab?
