Light and ReflectionLight is another type of wave that carries energy. A source of light (光源) such as the sun or a light bulb gives off light rays that travel away from the light source in all directions.A light ray is a narrow beam (光束) of light that travels in a straight line...
Light reflects from a smooth surface at the same angle as it hits the surface, this is known as the law of reflection. For a rough surface, the light rays scatter in different directions. Light rays are reflected in different directions because of changes in the surface plane, causing...
