| Term | Definition |
|---|
| what is the refraction of the sun viewed as when looking at it from underwater | it looks higher than it is |
| if a ray of light is refracted when entering B, what is the speed of light for A | the speed of light can be greater or less than B's |
| If a ray refracts when entering into a substance, when exiting, it cannot | be the normal, bend away from the normal, not bend at all |
| If an angle is reflected AND refracted, how do you find the angle b/w the reflected and refracted ray | . make external reflected ray equal to the incident . find the angle b/w substance & reflected ray . reflect previous angle in substance . answer is b/w total of twin angles or those added to reflected angle |
| what determines a high index of refraction | bending toward the normal |
| what determines a low index of refraction | bending away from the normal |
| how to find index of refraction if speed of light is given | N= c/v |
| what do n, c, and v represent in refraction equation | n= index of refraction c= 3 x 10^8 v= speed of light in substance |
| what does n=c/v get you? | index f refraction for angle 2 to plug into snell's law |
