Snell's law[SOLVED] 1. A ray of light travels from air(which is given to be 1.0003 I also had it be N1) into a liquid. The ray is incident upon the liquid(n2) at an angle of 30 degrees. The angle of refraction is 22 degrees. Indices of Refraction. Medium. . . .N Vacuum......1.00 Air.. . . . ....1.0003 Water.........1.33 Ethanol.......1.36 Crown Glass.1.52 Quartz........1.54 Flint Glass---1.62 Diamond-----2.42 2. n1 X sinO1= n2 X sin02 3. n1 X sinO1= n2 X sin02 Alright so I am given the O1, O2, N1, but not N2 so I will plug in the numbers. 1.0003 X sin(30)= N2 X sin(22) Then I continue to do the math 1.0003 X -0.988031624 = N2 X -0.00885130929 -0.988328033= N2 x -0.00885130929 so N2= 111.658965 My main problem is that the math doesn't any of the mediums we are given. Did I make a mistake in my work or is the book wrong? I have gone over this many times with myself.
