Question

What does the angular magnification (M) of a magnifier represent?
Options
A The ratio of the image size to the object size.
B The ratio of the angle subtended with the magnifier to the angle subtended without the magnifier.
Correct Answer
C The product of the focal lengths of the lenses.
D The sum of the magnifications of multiple lenses.
Correct Answer

Option B is the correct answer.

Detailed Explanation

According to the text, 'The angular magnification is M (angular magnification)=θ΄/θ where θ' = angle subtended with magnifier. θ = angle subtended without magnifier.' This directly defines angular magnification as the ratio of the angle subtended with the magnifier to the angle subtended without it.

Hint

Refer to the definition provided under 'The Magnifier' section, specifically the formula for angular magnification.
