A compound microscope has an objective of focal length 4 mm and an eye-piece of focal length 25 mm. The objective produces a real image at a distance of 180 mm. If the eye-piece is in normal adjustment the magnification is

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 compound microscope consists of an objective of focal length 1 cm and an eye-piece of focal length 5cm . An object is placed at a distance of 0.5cm from the objective. What should be the separation between the lenses so that the microscope projects an inverted real image of the object on the screen 30 cm behind the eye-piece ?

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
