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