Light Refraction - At first Brian was unable to
catch the fish because the water made them appear in a different location than where they
really were. This is due to light refraction in the water. Below is a demonstration of how
light refraction works.

Things To Try
- The incident angle can be varied from 0 to 85 degrees. (In 5 degree increments using the
- The index of refraction of the first medium is fixed at n=1.00.
- The index of refraction of the second medium can be varied from n=1.00 (for vaccuum) to
a maximum of n=2.42 (for diamond). (Selectable by pulldown menu.)
- The incident wavelength (and color of light) can be varied from a minimum of 475 nm
(blue light) to a maximum of 650 nm (red light). (In 15 nm increments using the +-15
- Notice that the refracted wavelength is shortened by a factor of 1/n.
