Power Of Compounding

Lateral magnification of objective of compound microscope is 100 and angular magnification of its eyepiece is 20. The magnifying power of compound microscope is

When the final image is formed at infinity the magnifying power of compound microscope is (using new Cartesian sign conventions)

The magnifying power of compound microscope in terms of the magnification m_0 due to objective and magnifyging power m_E by the eye-piece is given by

Which of the following is NOT an expression for magnifying power of compound microscop when final image is fomed at distace of distinct vison ? ( using new Cartesian sign conventions)

A compound microscope uses an objective lens of focal length 4 cm and eye lens of focal length 10 cm . An object is placed at 6 cm from the objective lens. Calculate magnifying power of compound microscope if final image is formed at the near point. Also, calculate length of the tube of compound microscope.

A compound microscope has tube length 300 mm and an objective of focal length 7.5 mm and an eyepiece of certain focal length. When eyepiece is replaced by another lens of focal length 20 mm, the magnifying power of compound microscope is increased by 100. The focal length of previous eyepiece is

The magnifying power of a compound microscope is

The resolving power of a compound microscope will increase with

The magnifiying power of a compound microscope increase with
