Question

What are the characteristics of the final image formed by a compound microscope?

Answer 1

Hint: In order to deal with this question first we will discuss the Compound microscope further then we will see how the objective lens of the compound microscope forms a real image. We will see the characteristics of an image on the basis of position and size as well as the image.

Complete answer:
Compound Microscope is an optical device which uses two lenses, primary lens forms a real image and a secondary lens is used as a magnifier to make an enlarged virtual image. When an object is placed farther from a converging lens than the focal length, the lens produces an inverted, real image and enlarged image, depending how close the object is to the focal point.

The objective lens produces a real image of the object, by having the object be just beyond its focal length and the eyepiece will then be placed very close to the image, so that the image falls within the eyepiece’s focal length and is Virtual, inverted and enlarged.
The process of the formation of the image can be understand properly by following diagram,

Hence, the characteristic of the final image formed by a compound microscope is virtual, inverted and enlarged.

Note:
Both the lenses in the compound microscope are convex lenses. Further the distance between the two lenses of the compound microscope can be shifted as closer and farther in order to obtain the clear image and also to change the magnification of the microscope. The microscope is used as an instrument to view objects which are too small to be seen by the naked eye. It helps us to perform studies, to study other microorganisms, cells and their structures, to make diagnoses and so on.
