is the compound microscope at normal adjustment the same as a telescope?

Dear student,

No these are not exactly the same..

The magnifying power of a compound microscope is defined as the ratio of the size of the final image (I₂) as seen through the microscope to the size of the object as seen with a naked eye.

Image Formation in a Compound Microscope

= m_objective x m_eyepiece

= m_o x m_e

Where m_objective (m_o) and m_eyepiece (m_e) are the magnification produced by the objective and eyepiece respectively.

m = m_o x m_e

Eye piece is nothing but a simple microscope

The lens formula is

But distance between the object and the lens is -u.

Multiply equation (2) by V

m = m_o x m_e
