Question

2. Below is a drawing showing a portion of a ray of light that starts in glass, then is refracted into air: glass, n-1.51 air a) On the above drawing, draw the normal lines (both on the glass side and on the air side). b) On the above drawing, indicate which angle is the incident angle I. c) On the above drawing, measure the incident angle I to the nearest 0.1°. d) Determine what the refracted angle R should be. Show your work. e) On the above drawing, draw the refracted ray at the proper angle, and indicate which angle it is.

Answer 1

" Angle b/w incident ray and Normal, as indicated above. I cannot do this part on computer screen. You have to do it on the paper using ""protractor"". You have to measure the angle it makes with the Normal is will assume any random angle to assist you further. Let I = 40 degree Use snell�s law n_glass sin I = n_air sin R = > 1.51 sin 40 degree = 1. Sin R R = sin^-1 (1.51 times sin 40 degree) = 76.0 degree \r\n Final Figure Fill look like this "
