Characteristics of Microscope and Telescope

There are many things in front of us that we cannot we with our eyes. A microscope is an instrument by which these bodies can clearly be seen by magnification. So, it is an optical instrument used for viewing very small objects, such as mineral samples or animal or plant cells, typically magnified several hundred times.

The optical instrument which is used to see a distant object clearly is called telescope. It has lenses inside it that make distant things seem larger and nearer when you look through it.

Characteristics of Microscope

  • It is used for observing very small object nearby.
  • Aperture and focal length of the objects are smaller than those of the eyepiece.
  • The image is magnified more or less by both the objective and the eye-piece.
  • The image of the object formed in the objective is at a distance greater than its focal length.
  • The final image is inverted with respect to the object.

Characteristics of Telescope

  • It is used to observe objects at a long distance.
  • Aperture and focal length of the objects are larger than those of the eye-piece.
  • The smaller image is formed in the objective than the object and that image is formed by the eye-piece.
  • The image in the objective is at its focal plane.
  • In some telescopes the image is erect, and in some telescopes, it is inverted with respect to the object.
