COMPOUND MICROSCOPE – NUMERICAL

TABLE OF CONTENTS

COMPOUND MICROSCOPE:

The compound microscope consists of a long cylindrical tube in which one end of the tube has an objective lens (small aperture and small focal length)  and the other end has an eyepiece lens (the aperture and the focal length are somewhat larger than the objective lens).

Objective lens which focuses a real image of the object,the image is further magnified by the  eyepiece which gives the viewer an image  that is virtual, magnified and inverted concerning the object(AB).

NUMERICAL-1

The objective lens and the eyepiece used in a compound microscope are of focal lengths 4 cm and 10 cm respectively.An object is placed at a distanceof 6 cm from the objective lens.What will be the magnifying power and length of the compound microscope?

NUMERICAL-2

The objective lens and the eyepiece used in a compound microscope are of focal lengths 2 cm and 3 cm respectively.The distance between objective lens and the eyepiece lens is 15 cm.The final image is formed at infinity.What is the distance of the object and image produced by the objective from the objective lens?
