Question

The index of refraction of Sophia's cornea is 1.421 and that of the aqueous fluid behind the is 1.396. Light is incident from air onto her cornea at an angle of 14.3 degree from the normal to the surface a) Calculate the angle of refraction of the incident light at her: Calculate the angle to the normal for the light traveling in the aqueous fluid. Siu - Ling has a far point of 25 cm. Which statement here is true? A) She may have normal vision. B) She is myopic and requires diverging lenses to correct her vision. C) She is myopic and requires converging lenses to correct her vision. D) She is hyperopic and requires diverging lenses to correct her vision. E) She is hyperopic requires converging lenses to correct her vision.

Explanation / Answer

Q16.

Using Snell's Law,

sin i/sin r = m*refrative index
r = arcsin((sin14.3)/1.421)
=> r = 10.02 degrees

aq = arcsin((sin14.3)/1.396)
=> aq = 10.2 degrees
