	The maximum magnification that can be obtained with a convex lens of focal length 2.5 cm is (the least distance of distinct vision is 25 cm)
	When the object is self-luminous, the resolving power of a microscope is given by the expression
	The power of two convex lenses A and B are 8 diopters and 4 diopters respectively. If they are to be used as a simple microscope, the magnification of
	Finger prints are observed by the use of
	To produce magnified erect image of a far object, we will be required along with a convex lens, is
	In order to increase the magnifying power of a compound microscope
	If the focal length of the objective lens is increased then
	The magnification produced by the objective lens and the eye lens of a compound microscope are 25 and 6 respectively. The magnifying power of this microscope is
	The focal lengths of the objective and the eye-piece of a compound microscope are 2.0 cm and 3.0 cm respectively. The distance between the objective and the eye-piece is 15.0 cm. The final image formed by the eye-piece is at infinity. The two lenses are thin. The distances in cm of the object and the image produced by the objective measured from the objective lens are respectively
	Resolving power of a microscope depends upon
