As shown at right below, a laser is directed into a water tank (filled with water having an index of refraction n2 at the laser wavelength) at an angle θ1 from the vertical and strikes the bottom of the tank at point A, a horizontal ditance r away from B, the spot directly underneath the place where the light enters the water. The distance r is:
