Question
Ater passing through the pane of glass the red and blue components are slightly offset. 29.9 By what angle (0cornea) is the beam of light shown in Fig- ure 29.16 deviated dent angle is = 23.6?The refractive index of air is nair = 1.00, the refractive index of the cornea is ncorea 1.38. Ignore further deviation of light as it passes from the cornea into the aqueous hu- as it passes from air to the cornea if the inci- mour, etc. Aqueous humour n 1.34 Air n=1.00 humour n= 1.34 Cornea n 1.38 lamp ll and m its Lens n= 1.39 to 1.41 own very Figure 29.16 Most of the bending of light in the eye is done at the air-cornea eir fi- interface. The lens is responsible for only a small amount of the bending, but of same course is adjustable. t the ivers 29.10 The ability of your eyes to focus is impaired when you at- tempt to look around underwater (if you are not wearing a pair of swimming goggles). Recalculate your answer for Problem 29.9 for the case in which the eye is submerged in water (nwater = 1.33). flec- fore. 1.0,Explanation / Answer

from snlts law
n1 sin theta1 = n2 sin theta 2
1xsin23.6 = 1.38 sin theta2
theta 2 = 16.86
theta cornea = 23.6-16.86 = 6.73 degree answer
10)
1.33 sin 23.6 = 1.38 sin theta 2
theta 2 = 22.69 degree
theta cornea = 23.6 -22.69
theta cornea = 0.9038 degree answer
