PHY 104 Refraction Through Lenses and Optical Instruments Objective Question
Take CBT

Question

In the Lensmaker's Equation, what do the terms R₁ and R₂ primarily represent?
Options
A The focal lengths of the two lenses in a system.
B The refractive indices of the lens material and the surrounding medium.
C The radii of curvature of the two surfaces of a single lens.
Correct Answer
D The object and image distances for the lens.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 24 states that the lensmaker's equation 'relates the radii of curvature of the two lens surfaces, and the index of refraction, to the focal length.' Thus, R₁ and R₂ represent the radii of curvature of the lens surfaces.

Hint

Recall the parameters involved in the Lensmaker's Equation as introduced on page 24.
