The focal lengths of objective and the eyepiece of a compound microscope are `f_(o)` and `f_(e)` respectively. Then,

The focal length of the objective and of the eye- piece of compound microscope are f_(0) and f_(e) respectively. If L is the tube length and d, the least distance of distinct vision, then its angular magnification, when the image is formed at infinity, is

The focal lengths of the objective and the eyepiece of a compound microscope are 2.0cm and 3.0cm, respectively. The distance between the objective and the eyepiece is 15.0cm. Th final image formed by the eyepiece is at infinity. The two lenses are thin. The distance, in cm, of the object and the image produced by the objective, mesured from the objective lens, are respectively.

The focal lengths of the objective and the eyepiece of a compound microscope are 1 cm and 5 cm respectively. An object is placed at a distance of 1.1 cm from the objective. For getting the final image at infinity, the distance between the two lenses, should be

The focal lengths of objective and eyepiece of a compound microscope are 0.5 cm and 1.5 cm respectively . If the least distance of distinct vision is 25 cm and magnification is 500 then what is the distance between objective and eyepiece?
