Snell's Law – with accurate answers (verified) Graded A

Refraction of light - Answers-The change of direction that a ray undergoes when it enters a medium obliquely where the speed of the waves changes. medium - Answers-A transparent material like air, water, and glass through which light can travel index of refraction (n) - Answers-the ratio of the speed of light in a vacuum (c) to the speed of light in a medium (v) Snell's Law - Answers-n1sinθ1 = n2sinθ2 n1 represents the index of refraction of the first medium. sin θ1 represents the sine of the angle of incidence. Check to be sure that your calculator is in degree mode. n2 represents the index of refraction of the second medium. sin θ2 represents the sine of the angle of refraction. Air index of refraction - Answers-For air, the index of refraction is equal to 1, because the speed of light in air is nearly equal to the speed of light in a vacuum. Light travels at different speeds in different media. - Answers-When light enters a medium with a higher index of refraction than the medium it is leaving, it bends toward the normal. When light enters a medium with a lower index of refraction than the medium it is leaving, it bends away from the normal.
