Take CBT

Question

Which of the following descriptions accurately characterizes a diverging lens?
Options
A Thicker in the center than at the edge, and causes parallel light rays to converge.
B Thinner in the center than at the edge, and causes parallel light rays to diverge.
Correct Answer
C Has a uniform thickness throughout, and does not significantly refract light.
D Thicker in the center than at the edge, and causes parallel light rays to diverge.
Correct Answer

Option B is the correct answer.

Detailed Explanation

According to page 6 and the diagrams on page 4, a diverging lens is thicker at the edge than in the center and makes parallel light diverge. Option B correctly describes this.

Hint

Think about the effect of a diverging lens on parallel light rays and its characteristic shape mentioned on page 4 and 6.
