2. A light ray travels from glass (n=1.6) to water (n=1.33), then to a net glass (n=1.45) a. Draw the line normal to the surface and label the angle b. Calculate the angle of refraction on this first surface Draw the path the light ray takes as it moves through the glass and emerges on the other side. d. Determine the angle of incidence and refraction on the second surface. 402
