A compound microscope consists of an object lens of focal length 2 cm and an eyepiece of focal length 5 cm. When an object is placed at 2.2 cm from the object lens, the final image is at 25 cm from the eye lens. What is the distance between the lenses ? What is the total linear magnification ?

A compound microscope has an objective lens of 1.0 cm focal length and an eye-piece of 2.5 cm of focal length. When the object is placed at 1.1 cm from the objective, the final image is at the least distance of direct vision. Thus, the magnification produced is

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