Unformatted text preview: Refraction of Light s The incident ray, the reflected ray, the refracted ray, and the normal all lie on the same plane s The angle of refraction, 2 , depends on the properties of the two media Following the Reflected and Refracted Rays s Ray 1 is the incident ray s Ray 2 is the reflected ray s Ray 3 is refracted into the lucite s Ray 4 is internally reflected in the lucite s Ray 5 is refracted as it enters the air from the lucite Refraction-putting on the brakes s Light may refract into a material where its speed is lower s The angle of refraction is less than the angle of incidence s The ray bends toward the normal Refraction-accelerating s Light may refract into a material where its speed is higher s The angle of refraction is greater than the angle of incidence s The ray bends away from the normal The Index of Refraction s When light passes from one medium to another, it is refracted because the speed of light is different in the two media s The index of refraction, n, of a medium...
