  1. Question 1

    Q1. The magnifying power of a simple microscope can be increased by:

    • A) Increasing the focal length of the lens
    • B) Decreasing the focal length of the lens
    • C) Using a lens of large aperture
    • D) Using a lens of short aperture

    Answer: Decreasing the focal length of the lens

    Explanation: Magnifying power of a simple microscope = 1 + D/f (where D = 25 cm, f = focal length); decreasing f increases the magnifying power, so a shorter focal length lens produces greater magnification.
