Calculate magnifying power of a simple microscope of focal length 5 cm. (Given D = 25 cm)

For relaxed eye,magnifying power of a microscope is

Define the magnifying power of compound microscope.

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.

Power of a lens is -5d, its focal length is:

A compound microscope with an objective of 1.0 cm focal length and an eye-piece of 2.0 cm focal length has a tube of lengh of 20 cm.Calculate the magnifying power of the microscope,if the final image is formed at the near point of the eye.

An angular magnification (magnifying power) of 30X is desired using an objective of focal length 1.25cm and an eyepiece of focal length 5cm. How will you set up the compound microscope?

The focal length of th eye-piece and ojective a compound microscope are 5 cm and 1 cm respectively and the length of the tube is 20 cm.Calculate he magnifying power of the microscope,when the final image is formed at infinity .The value of least distance of ditinct vision is 25cm.

Answer the following questions: Magnifying power of a simple microscope is inversely proportional to the focal length of the lens. What then stops us from using a convex lens of smaller and smaller focal length and achieving greater and greater magnifying power?
