Explain the construction of Simple Microscope.

Explanation

(i) Simple microscope : Simple microscope has a convex lens of short length. It is held near the eye to get enlarged image of small objects.
(ii) Let an object (AB) is placed at a point within the principal focus `(mu lt f)` of the convex lens and the observer's eye placed just behind the lens.
(iii) As per this position the convex lens produces a erect , virtual and enlarged image (A'B') . The image formed is in the same side of the object and the distance equal to the least distance of distinct vision (D) (D=25 cm for normal human eye)
