The cornea and lens of the human eye are described as acting together in what way?
AAs two completely independent lenses focused on different retinas
BAs a system that, to a good approximation, acts as a single thin lens
CAs a pair of mirrors rather than a pair of lenses
DAs filters that block all light except a narrow visible band
Answer & Solution
Correct answer: B. As a system that, to a good approximation, acts as a single thin lens
1. The cornea and the lens together form a system that, to a good approximation, acts as a single thin lens.
2. This lets the same thin-lens equations used for mirrors and simple lenses apply to the eye.
3. The cornea and lens are not mirrors and are not simple light-blocking filters, so those options misdescribe their role.
