(@) Spectacles are often coated to reduce reflection. The plastic of the lens has a very thin coating of some other material with different refractive index (as shown in the figure). 11 T2 Air ni Coating TLV n2 Lens n3 Figure - cross section showing three parallel layers of material (air, coating and the lens), with a light ray incident on the coating. The ray is partially reflected at the air/coating interface; the reflected ray Ti is shown....

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...
