Explanation Microscopes are devices used to magnify tiny objects. The construction of the microscope is similar to that of the telescope. The objective produces a real and inverted image of the object, which falls between the focus and the optic centre of the eyepiece. The eyepiece produces an enlarged virtual image of the image formed by the objective. The final image formed is inverted and enlarged. The magnification of the microscope is the product of the magnifications of the objective and the eyepiece. Using the thin lens formula, a relation between the object distance d o and the focal length of the objective f o is determined. 1 f o = 1 d o + 1 d i The magnification m o of the objective is given by, m o = d i d o Using the given values of the focal length, the maximum and the minimum values of m o are determined and these values when multiplied by the maximum and the minimum values of the magnification of the eye piece give the values of the maximum and the minimum possible values of magnification of the microscope. M = m o × m e Given: The values of the objective focal lengths f o = 32 mm, 15 mm and 3 .9 mm The values of the magnifications of the eyepiece m e = 5 × , 15 × The distance from the objective at which the image is formed by it d i = f o + ( 160 mm ) Formula: 1 f o = 1 d o + 1 d i m o = d i d o M = m o × m e Calculation: Derive a relationship between the object distance and the focal length of the objective using the thin lens equation, by substituting d i = f o + ( 160 mm ) in the thin lens equation...

Lateral Magnification

In very simple terms, the same object can be viewed in enlarged versions of itself, which we call magnification. To rephrase, magnification is the ability to enlarge the image of an object without physically altering its dimensions and structure. This pr…
