Refraction problem 7

A lightbulb glows at the bottom of a pool. The bulb glows on all sides, but only some part of the light penetrates the air. Describe the course of the following rays:

  • a ray passing vertically from the pool into the air,

  • a ray passing into the air at an angle,

  • a ray along the water-air boundary,

  • a ray that bounces off the surface back into the water.
