In order to increase the angular magnification of a simple microscope, one should increase
View answer and explanation
Correct option: D
The power of the lens
Option D (The power of the lens) is correct because angular magnification of a simple microscope is inversely proportional to the focal length, and power is inversely proportional to focal length. Therefore, increasing the power increases the magnification.

An object 5 cm tall is placed from a concave spherical mirror which has a radius of curvature of . The size of the image is
Red colour is used for danger signals because
A ray of light is incident on the hypotenuse of a right-angled prism after travelling parallel to the base inside the prism. If is the refractive index of the material of the prism, the maximum value of the base angle for which light is totally reflected from the hypotenuse is
Statement-A: The minimum distance between an object and its real image formed by a convex lens is .
Statement-B: The distance between an object and its real image is minimum when its magnification is -1. Assertion: We cannot produce a real image by plane or convex mirrors under any circumstances.
Reason: The focal length of a convex mirror is always taken negative. If both the object and image are at infinite distance from a refracting telescope its magnifying power will be equal to
