What is the index of refraction of a refractive liquid if the angle of incidence in the AIR is 35 degrees and the angle of refraction is 14 degrees? What is the correct way to solve?
n (sin35) = (1)(sin14) ...n=0.42
n (sin35) = (1)(sin14) ...n=2.37
(1)(sin35) = n (sin14) ...n=2.37
(1)(sin35) = n (sin14) ...n=0.42

Light traveling through air encounters a second medium which slows the light to makes the index of refraction 1.6. What is the velocity of light in the second medium? Which is the correct way to set up and solve this problem? n=c/v.....v=c/n.....c=3E8 m/s
n = 3E8 / 1.6
n = 1.6 / 3E8
v = 3E8 / 1.6
v = 1.6 / 3E8
Glass has a _____________ index of refraction (or "n") than air.

According to Willebord Snell, light passing from air to glass will cause the light to

If light is traveling from air to water and has an angle of REFRACTION of 30 degrees, what is the angle of INCIDENCE? (n=1 air, n=1.33 water) Which is set up correctly?
(1)(sin30) = (1.33)(sinƟ)....
.....sinƟ = (1)(sin30) / 1.33
(1)(sin30) = (1.33)(sinƟ).....
.....sinƟ = 1.33 / (1)(sin30)
(1)(sinƟ) = (1.33)(sin30)......
....sinƟ = (1.33)(sin30) / 1
(1)(sinƟ) = (1.33)(sin30).....
.....sinƟ = 1 / (1.33)(sin30)
