INTRODUCTION TO MICROSCOPE: A microscope (from the Greek: mikrós, "small" and skopeîn, "to look" or  "see") is an instrument used to see objects that are too small for the naked eye. MICROSCOPY: The science of investigating small objects using such an instrument is called microscopy.Microscopic means invisible to the eye unless aided by a microscope.  MAGNIFICATION: For calculation of the total magnification when viewing an image with a light microscope, first take the power of the objective lens which is at 4x, 10x or 40x and then multiply it by the power of the eyepiece which is generally 10x. It means, a 10x eyepiece used with a 40x objective lens, will produce a magnification of 400x. Magnification is a measure of increase in diameter of an object. RESOLUTION : Resolution means the degree of detail. Resolving Power may be described as the ability to measure the separation of images that are close together. The shorter wavelength ensures in...
