1. A narrow stream of radiant energy, especially visible light, traveling in a straight or nearly straight line. b. A narrow stream of particles such as protons traveling in a straight or nearly straight line.
2. Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection. For a rough surface, reflected light rays scatter in all directions. This is called diffuse reflection
3. Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection
