A compound microscope has an objective of focal length `2.0 cm` and an eye-piece of focal length `6.25cm` and distance between the objective and eye-piece is `15cm`. If the final image is formed at the least distance vision `(25 cm)`, the distance of the object form the objective is

A microscope has an objective of focal length 1.5 cm and eye piece of focal length 2.5 cm . If the distance between objective and eyepiece is 25 cm . What is the approximate value of magnification produced for relaxed eye ?

A compound microscope has an objective of focal length 2 cm and eye-piece of focal length 5 cm. The distance between the two lenses is 25 cm. If the final image is at a distance of 25 cm from the eye-piece, find the magnifying power of the microscope. What would be the magnifying power if the microscope were reversed ?

A microscope consists of an objective of focal length 1.9 cm and eyepiece of focal length 5 cm. The two lenses are kept at a distance of 10.5 cm. If the image is to be formed at the least distance of distinct vision, the distance at which the object is to be placed before the objective is (least distance of distinct vision is 25 cm)

A compound microscope has an eye piece of focal length 10 cm and an objective of focal length 4 cm . Calculate the magnification, if an object is kept at a distance of 5 cm from the objective so that final image is formed at the least distance vision (20 cm)

A compound microscope has an eye piece of focal length 10 cm and an objective of focal length 4 cm . Calculate the magnifcation, if an object is kept at a distance of 5 cm from the objective so that final image is formed at the least distance vision (20 cm)
