Air Second n - c/v and n1 sin01 = n2 sin 02 medium 11. Problem 1 of 4: A ray of light travels from air (nj = 1) into another medium, making an angle of = 42 with the normal. Using the figure above, find the angle of refraction 02 if the second medium is: Fluorite with n2 = 1.434 and use 02= Sin-1(n12 sin 01) 02 = O - 27.8 ~ 73.6 - 34.2' O - 62.2 - 37.812. Problem 2 of 4: A ray of light travels from air (n, = 1) into another medium, making an angle of = 42" with the normal. Using the figure above, find the angle of refraction 02 if the second medium is: Sapphire with n2 = 1.77 and use 02= Sin-1(n12 sin 01) 02 - _ _ O ~ 47.8 O ~ 27.8 - 22.2 ~ 67.8 - 31.213. Problem 3 of 4: A ray of light travels from air (nj = 1) into another medium, making an angle of = 42' with the normal. Using the figure above, find the angle of refraction 02 if the second medium is: Diamond with n2 = 2.42 and use 02= Sin-1(nj2 sin 01) Answer 0, = - 25.2. O ~ 22.2 - 20.05 O - 27.8 - 16.0514. Problem 4 of 4: A ray of light travels from air (n1 = 1) into another medium, making an angle of = 42 with the normal. Using the information from part 3 of the problem, for diamond, what is the velocity of light in the substance, using n = 2.42? v = c V = - 2.00 x 10^8 m/s - 1.24 x 10^8 m/s - 3.00 x 1018 m/s O - 3.3 x 10^8 m/s - 2.12 x 10 8 m/s
