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.
Explain the Friction Friction is a force that works against all motion. It slows everything down and it is the reason that the motion we are most familiar with always seems to

Coulomb: Coulomb is the fundamental unit of charge. It is explained as the charge required to obtain 9?109 newton of force among two equal charges separated at a distance of one m
Accelaration is the rate of change of velocity.It defines how velocity is chaging with respect to time.
