Consider the following statements   1. The focal length of the eyepiece is larger than the focal length of the objective. 2. The focal length of the eyepiece is smaller than the focal length of the objective. 3. The aperture of the eyepiece lens is larger than the objective lens. Which of the following statements is/are INCORRECT about a compound microscope?

Consider the following statements   1. The focal length of the eyepiece is larger than the focal length of the objective. 2. The focal length of the eyepiece is smaller than the focal length of the objective. 3. The aperture of the eyepiece lens is larger than the objective lens. Which of the following statements is/are INCORRECT about a compound microscope? Correct Answer Only 2

CONCEPT:

Compound microscope:

  • A compound microscope is an optical device used to see magnified images of tiny objects.
  • A good quality compound microscope can produce a magnification of the order of 1000.
  • It has two convex lenses- one of them is called as the objective lens and the other one is known as the eyepiece


EXPLANATION:

  • The focal length of the eyepiece lens is larger than the focal length of the objective lens. So statement 1 is correct and statement 2 is incorrect.
  • The aperture of the eyepiece lens is larger than the objective lens. So statement 3 is correct.
