PHY 104 The Human Eye Objective Question
Take CBT

Question

Referring to Additional Example 3, if the 2.0 diopter lens was a concave lens instead of convex, what would be the total power of the system?
Options
A +2.5 D
B -1.5 D
Correct Answer
C +1.5 D
D -2.5 D
Correct Answer

Option B is the correct answer.

Detailed Explanation

A concave lens has negative power. So, if the 2.0 diopter lens was concave, its power would be -2.0 D. The total power would then be the sum: P_total = +0.5 D + (-2.0 D) = -1.5 D.

Hint

Remember that concave lenses have negative power, and powers of lenses in contact are additive.
