Meaning of microscopic scale: microscopic scale can be stated as the contact between the particles and the scale of the particles. The rotations of the particles, the position of contact forces, the position of the point of contact and the centre of the particles are the variables that are taken into consideration at the microscopic scale. At the microscopic scale, the thermal energy expression of the energy of vibration is possessed by the atoms. The higher will be the thermal agitation of the atoms at a higher temperature.

The light microscopes let us view objects that are as small as 0.2 micrometres in size. On the other hand, powerful microscopes let us see the tiniest of objects. Even the objects of the size of the atom (about one angstrom in size). Thus, we can assume the microscopic scale to be ranging from one millimetre to ten-millionth of a millimetre.

There are tremendous alterations in the size of the microscopic objects even on the microscopic scale. Thus, it becomes important to note that while using a microscope one needs to know the magnification that is being used so that the actual size of the things can be determined.

At present, the smallest size of an object that can be determined with the help of a microscope is that of an atom. Any object that is smaller than the size of an atom is currently out of reach of the range electronic microscope. But, with the advancement of the newer technologies in the branch of microscopes, it is likely to determine the size of the objects that are smaller than the size of the atom on the microscopic scale.

The cells of plants and animals are that are of the size of twenty micrometres are visible on the microscopic scale of light microscopes. They can be viewed in great detail with the help of the electron microscope. The microscopes are of great help in understanding the growth and division of the cell.

Rocks are visible even with the naked eyes and there arises no necessity for the microscope to have a look at the rocks. But there are various microscopic particles present as the properties of the rocks that are not visible to the naked eyes. These tiny particles of the rocks can be identified with the help of a microscope. With the help of the microscope, it is possible for the research personnel to have a closer and a much-detailed look at the properties that are present and are helpful in the formation of the rocks. With the help of the microscopic study of the properties the determination of the age of the rocks can also be determined.

Conclusion:

Microscopes are the devices that are used to understand objects that are not visible to the naked eye on the part of humans. The scale of the microscopes varies as per their nature. Thus, different types of microscopes have been used to identify objects of different sizes. On one end a light microscope is used to identify an object of the size of 0.2 micrometres whereas on the other end powerful microscopes can identify objects of the size of an atom.
