A solid glass sphere with a radius of 8.00 cm and index of refraction of 1.50 has a small coin embedded 2.50 cm from the front surface of the sphere.For the viewer looking at the coin through the glass,at what distance from the front surface of the glass does the coin's image appear to be located?

Question

Quizplus · Accepted Answer

The image of the coin appears to be located 1.86 cm from the front surface of the glass. This is because the index of refraction of glass is greater than that of air, so the light rays from the coin are bent towards the normal when they enter the glass. This causes the image of the coin to appear closer to the front surface of the glass than the coin actually is.
