Question

The cornea of the human eye has refractive index1.38, while the eye's lens has a graduated index in the range 1.38 to 1.40; use 1.39 for this problem. For the aqueous humor between cornea and lens,n = 1.34.

Part A-

Find the angle through which light is deflected at the first surface of the cornea, if it's incident at 20 to the normal at each surface. Your result shows that the cornea is the dominant refractive element in the eye.

Express your answer using two significant figures

Answer is 5.7 degrees.

Part B-

Find the angle through which light is deflected at the first surface of the lens, if it's incident at 20 to the normal at each surface. Your result shows that the cornea is the dominant refractive element in the eye.

Express your answer using two significant figures.

(Just need part B)

Explanation / Answer

B)

from snelts law

1.34sin 20 = 1.39sin theta

theta = 19.25 degree

deflected = 20-theta

deflected angle = 0.748 degree answer
