# Microscope!

**Classical Mechanics**Level 4

The focal lengths of the eye-piece and the objective of a compound microscope are \(5\text{ cm}\) and \(1\text{ cm}\) respectively and the length of the tube is \(20\text{ cm}.\) Calculate the magnifying power of the microscope, when the final image is formed at infinity. The value of least distance of distinct vision is \(25\text{ cm}.\)
