A compound microscope has a magnifying power `30`. The focal length of its eye-piece is `5cm`. Assuming the final to be at the least distance of distinct vision `(25 cm)`, calculate the magnification produced by objective.

Text Solution

Verified by Experts

`m =- 30, f_(e) = 5cm`
`m_(e) = 1+(D)/(f_(e)) = 1+(25)/(5) = 6`
`m = m_(0)xxm_(e)`
`-30 = m_(0) xx 6 rArr m_(0) =-0 5`

A compound microscope has a magnification f 30. the focal length of its eyepiece is 5 cm. assuming the final image to be formed at least distance of distinct vision (25 cm), calculate the magnification produced by the objective.

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.
