Question

If a microscope has a $10\times$ objective lens and $10\times$ ocular lens, it would magnify the object by

• A. $10\times$
• B. $20\times$
• C. $50\times$
• D. $100\times$

Answer 1

The correct option is D $100\times$

The compound microscope is the instrument used to magnify the image of the object that we cannot see by naked eyes. It uses two lenses or lens systems, one is the objective lens which enlarged the image of the object and the second is an ocular lens which magnifies the image formed by the first. The total magnification is the product of the magnifications of two lens systems. Hence, the microscope which has a 10X objective lens and 10X ocular lens, it would magnify the object by 10 × 10 = 100 times.
