If the intensity ratio of two waves is 4 : 1, the ratio of their amplitudes will be

A man standing midway between two cliffs, claps his hands and starts hearing a series of echoes at intervals of one second. If the speed of sound in air is 340 ms^-1, the distance between the cliffs is

AB and CD are long straight conductors, distance d apart, carrying a current I. The magnetic field on BC due to the currents in AB and CD

An object is initially at a distance of 500 cm from a plane mirror. If the mirror approaches the object at a speed of 2 cm/s, then after 6 seconds, the distance between the object and its image will be

To obtain a magnified virtual image of an object by a convex lens of focal length f, the distance between the object and the lens should be
