Question

A microscope in which maximum magnification is achieved, but the object cannot be seen by eye is called:
A) Simple microscope.
B) Dissecting microscope.
C) Electron microscope.
D) Phase contrast microscope.
E) Compound microscope.

Answer 1

Hint: The microscope is an instrument which is used to see objects which are very small and cannot be seen by naked eyes. The science of dealing and exploring with very small objects is known as microscopy. There are different types of microscope which are used to see objects of different ranges.

Complete step by step solution:
It is asked in the problem that we need to tell which microscope is used to get maximum magnification of the image and the object cannot be seen by the naked eye. Let us consider each option and find out which is the correct option for this problem. The first option is a simple microscope.

A simple microscope is an instrument which uses a single lens to produce magnified images of an object which cannot be seen through naked eye. The magnification produced is not much as only a single lens is used. The second option is dissecting microscopes.

The dissecting microscope is the microscope which is used to see the magnified image of 3D objects; the maximum magnification produced by the dissecting microscope is x 100. The objects magnified by the dissecting microscope can be seen by the naked eye. The third option is electron microscopy.

An electron microscope is an instrument which uses an accelerated beam of electrons as a source of illumination. It can be used to magnify the objects which are in nanometers. It can be used to magnify objects which cannot be seen by the naked eye. The highest magnification can be achieved by the electron microscope. The fourth option is compound microscope.

A compound microscope is an instrument which uses two lenses to amplify the image of an object. The magnification is done for the two dimensional objects. The magnification of the compound lenses is x1000 which is less than an electron microscope. So the magnification produced by the microscope is the highest for an electron microscope.

The correct answer for this problem is option (C).

Note: The microscope is the arrangement of lenses in such a way that the object which is very small can be magnified and it becomes visible for the human eye. A simple microscope uses a single lens to magnify the object and the compound microscope uses two lenses to magnify the image.
