Question

Jupiter’s moon Europa is full of water. An astronaut investigating the moon finds a very long glass slab (nglass = 1.87) under water, perhaps left there by another alien visiting the moon. The actual thickness of the slab is 12 cm. What is the thickness of the slab as measured by the astronaut looking at the slab from almost normal incidence? The index of refraction of water, nwater = 1.33. Note: The figure is not drawn to scale

Answer 1
