The focal lengths of the eye piece and objective of a compound microscope are `5 cm and 1 cm` respectively, and the length of the tube is `20 cm`. Calculate magnifying power of microscope when the final image is formed at inifinity. The least distance of distinct cision is `25 cm`.

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.

The focal lengths of the objective and eyepiece of a microscope are 4mm and 25 mm respectively, and the length of the tube is 16cm. If the final image is formed at infinity and the least distance of distinct vision is 25 cm, then calculate the magnifying power of the microscope.

The focal lengths of the objective and the eyepiece of a compound microscope are 1 cm and 5 cm respectively and the distance between the centres of the lenses is 15 cm . If the final image is formed at the least distance of distinct vision , what is the magnifying power of the microscope ?

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 length of 20 cm . Calculate the magnifying power of microscope is final image is formed at the near point of eye.
