Monochromatic light (single wavelength) falls on two narrow slits S1 and S2 which are very close together acts as two coherent sources, when waves coming from two coherent sources (S1, S2) superimposes on each other, an interference pattern is verified on the screen. In YDSE alternate bright and dark bands obtained on the screen. These bands are known as Fringes.
Reflection of a Pulse at a Fixed End Let's assume a pulse moving by a medium - perhaps by a rope or a slinky. What happens to the pulse while it reaches the end of that medium?
Assume a crane lifts a 900 kilogram wrecking ball 12 meters above a concrete slab. 105,840 Joules of potential energy are kept in the wrecking ball. Now the ball is dropp

Why we feel sky blue in color? The blue color of the sky is because of Rayleigh scattering. As light moves by the atmosphere, most of the longer wavelengths pass straight thr
In a certain cathode-ray tube, a beam of electrons, moving at a constant velocity, enters a region of constant electric force midway among two parallel plates that are 10.0 cm long
