Refraction (pulled from 8.2 deck)

Question 1

refraction

Answer 1

the bending of light as it passes from one medium to another and changes speeds

Question 2

index of refraction for a given medium (equation)

Answer 2

Question 3

snell’s law

Answer 3

Question 4

critical angle

Answer 4

when the refracted angle equals 90 degrees

the refracted light ray passes along the interface between the 2 media and never escapes the medium

Question 5

how to calculate the critical angle

Answer 5

use snells law and let the second angle = 90
sin (90) = 1

Question 6

total internal reflection

Answer 6

a phenomenon in which all the light incident on a boundary is reflected back into the original material

Results when the incident angle is greater than the critical angle
