if we change the lenses of compound microscope then why it is not act as telescope?

Dear Rajat,

YES a compund microscope can act lik a telescope if you chnage the lens,

While telescopes and microscopes both have long tubes which hold the lens, a telescope has a larger objective lens, or lens closest to the object. On a microscope, this lens must be smaller for magnification and to be able to move in close to the object being studied. This allows the microscope to catch the light rays from the object to make the image.

if u change the lens of a compund microscope(which is the main difference between telescope and compund microscope) it will act as a telescope

Compound Microscopes
# Widely used in fields such as biology, bacteriology and medicine, the compound microscope is used to view such minuscule items as bacteria. The compound microscope has at least two convex lenses. Each lens is then attached to either end of a long cylinder forming the compound microscope. Other lenses may be added for additional magnification. The lens closest to the object is called the objective. The lens closest to you is called the eyepiece. Compound microscopes are mounted upright on a screw device, which allows the user to focus the microscope effectively.

Telescope

# Microscopes are closely related to the telescope. A microscope today looks very similar to the Kelperian telescopes of history. The eyepieces, or lenses closest to the eye, are almost exactly the same. However, there are some differences between the telescope and the microscope. While telescopes and microscopes both have long tubes which hold the lens, a telescope has a larger objective lens, or lens closest to the object. On a microscope, this lens must be smaller for magnification and to be able to move in close to the object being studied. This allows the microscope to catch the light rays from the object to make the image.
