Using Figure 9.7 and a protractor, draw the refracted rays that exit the curved surface of the lens. Assume that the light is traveling through the air into the lens and then back out into air. Also assume that the lens is made of acrylic. Describe what happens to the refracted rays,and whether they converge to a point.

water interface (the surface of the lake), it is partly
reflected back into the air and partly refracted
or transmitted into the water. This explains why on the surface of
a lake sometimes you see the reflection of the surrounding
landscape and other times the underwater vegetation.

5. The critical angle is 40°at the interface from plastic to air. Figure 11 shows a light ray is incident on the top surface of the plastic block. Draw on Fig. 11 the ray path inside the plastic block until it emerges from the block. All the refraction and reflection angles should be drawn to scale using a protractor 15 Air Plastic Figure 11

Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...
