scatteringIn physics, the change in direction of motion of a particle because of a collision with another particle. The collision can occur between two charged particles; it need not involve direct physical contact. Experiments show that the trajectory of the scattered particle is a hyperbola and that, as the bombarding particle is aimed more closely toward the scattering centre, the angle of deflection decreases. The term scattering is also used for the diffusion of electromagnetic waves by the atmosphere, resulting, for example, in long-range radio reception on the ground. See also Rayleigh scattering. |

| The four shots came in rather a scattering volley, but they did the business: one of the enemy actually fell, and the rest, without hesitation, turned and plunged into the trees. The children got to know his figure, and the sparrows expected their daily scattering of bread- crumbs. For instance, to scatter seed is called sowing: but the action of the sun in scattering his rays is nameless. |
