A microscope is focused on a mark on horizontal surface. A rectangular glass block 30mm thick is
place on the mark. The microscope is then adjusted dd10mm upwards; to bring the mark back to
focus, determine the refractive index of the glass

Apparent depth = 30 – 10 = 20cm
real depth / Apparent depth= 30/20
=1.5
