Magnification of a compound microscope is 30. Focal length of eye`-` piece is `5 cm` and the image is formed at a distance of distinct vision of `25 cm`. The magnificatio of the objective lens is

The magnification produced by the objective lens of a compound microscope is 25. The focal length of eye piece is 5 cm and it forms find image at least distance of distinct vision. The magnifying power of the compound microscope is

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.

A compound microscope produces a magnification of 24. The focal length of the eyepiece is 5 cm. The final image is formed at the least distance of distinct vision. What is the magnification produced by the objective ?

What is the magnifying power of a simple microscope of focal length 5 cm, if the image is formed at the distance of distinct vision ?

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.

The focal length of the objective of an astronomical telescope is 75 cm and that of the eye-piece is 5 cm. If the final image is formed at the least distance of distinct vision from the eye, calculate the magnify- ing power of the telescope.

The magnifying power of a simple microscope is 6. The focal length of its lens in metres will be, if least distance of distinct vision is 25cm

In an astronomical telescope, focal length of eye piece is 5 cm and focal length of objective is 75 cm . The final image is formed at the least distance of distinct vision (=25 cm) from the eye. What is the magnifying power of the telescope ?
