A Circular Track of Radius r What is the distance covered by the athelete when he reaches the point B? The distance covered by the athlete when he reaches the point B ..

The field lines are circles concentric with the wire. The magnitude of the magnetic field due to a N-turn circular coil of radius R carrying a current i at an axial distance x from the center is At the center this reduces to Ampe..

Consider a parallel beam of light from a lens falling on a slit AB. As diffraction occurs, the pattern is focused on the screen XY with the help of lens L 2 . Each point on the unblocked portion of plane wavefront AB sends out secondary wavelets in all directions. The waves from ..

>, which therefore begins to vibrate. After a time , P 3 picks up the vibration. In this way, after a time T, the disturbance will have just reached P 9 . At this stage, P 1 and P 9 will be in the same state of vibration or will be in phase. The trough (valley) and the crest (hump) togeth..

Intensity and Loudness of Sound - Physically, a wave involves the propagation of energy. This transfer of energy by a traveling wave is expressed in terms of the intensity I. Intensity of sound waves is defined as the average energy transported per second per unit area perpendicular to the directio..

>When final image is at the least distance of distinct vision from the eye, the magnifying power is given by In a terrestrial telescope, final image has to be made erect with respect to the object. For this, we have to use an erecting lens between objective lens and eye lens. Expressions ..
