A paperweight consists of a cylinder of glass (n = 1.5) 1.00 cm high and of radius 2.00 cm on which is mounted a hemisphere of radius 2.00 cm. The weight is placed on a sheet of paper so that an inkspot is at the centre of its plane surface C. Looking from above, how far below the upper surface of the glass will the spot appear to be?
Hint: Draw a light ray originating at C and stick rigorously to the sign convention.
