A particle is said to move with uniform velocity if it undergoes equal displacements in equal intervals of time, however small these intervals may be. In this case, the velocity is equal to the displacement vector per unit time interval and is given by When a particle moves ..

Let us consider a single particle, whose position with reference to the origin O of the two-dimensional coordinate system is given by position vector . The location of the particle is P (x, y). Let q be the angle between OP and X-axis. Suppose a force applied on the particl..

>- A surface touching these secondary wavelets tangentially in forward direction at any instant gives the new (secondary) wave front at that instant. Using Huygenss principle, we can prove the laws of reflection and the laws of refraction on the basis of the wave theory. Superposition principle say..
