- = The figure is shown TO SCALE. Each block represents a 1.00 cm square. It shows a ray of light entering a rectangular piece of glass (n₂ 1.50) from air (n₁ = 1.00). Find the position (x,y in cm) where the ray exits the glass. Or, if it does not exit the glass, find the (x,y) position of the second point (the second reflection) where total internal reflection occurs. In either case, be sure to check if total internal reflection occurs.

- The law of reflection is given by the equation: e1= The angle of incidence at a rare medium e = The angle of reflection at the rare medium 02 = The angle of refraction at a denser medium nz= The index of refraction of the rare medium n2 = The index of refraction of the denser medium O ni Sine1 = n, Sine2 O 81 =02 O 01 = 0 O ni Sine 2 = n2 Sine1A prism made of flint glass has a cross section that is an equilateral triangle. The index of refraction for red and violet light respectively in flint glass is 1.662 and 1.698. If as shown in the figure, the angle of incidence in air for both colors of light is 66.8°, determine the angle at which both colors emerge back into air after traveling through the prism. red light ° violet light °As shown in the figure, a light beam travels from air, through olive oil, and then into water. If the angle of refraction 82 for the light in the olive oil is 34.8°, determine the angle of incidence e, in air and the angle of refraction e3 in water. The index of refraction for olive oil is 1.47. 83 = air oil water
