Define the magnifying power of compound microscope.

Define the magnifying power of a compound microscope when the final image is formed at infinity. Why must both the objective and the eye piece of a compound microscope has short focal length? Explain.

A compound microscope uses an objective lens of focal length 4 cm and eyepiece lens of focal length 10 cm. An object is placed at 6 cm from the objective lens. Calculate the magnifying power of the compound microscope. Also calculate the length of the microscope.

With the help of labelled diagram, give the principle and magnifying power of compound microscope, when final image is formed at least distance of distinct vision.

Define resolving power of a compound microscope. How does the resolving power of a compound microscope change when wavelength of radiation used is increased.
