Problem 34.1: Find index of refraction, two mediums

Please wait for the animation to completely load.

A beam of parallel rays is shown passing through a medium surrounded by air. Both the position of the source and the angle of the source rays can be adjusted by click-dragging the circular hotspots. You can move the pink protractor around and use it to measure angles (position is given in meters and angle is given in degrees). Restart.

  1. What is the index of refraction of the inner medium?
  2. What is the angle of total internal reflection for the inner medium?
