Angle of reflection - the angle between the incident ray and the normal to the surface. Incandescent bulb - a source of artificial light that works by releasing the thermal radiation from a body due to its temperature. Specular reflection - reflection from a smooth surface, in which the light ray leaves at the same angle at which it came in. Incidence ray – a ray of light which hits a surface. | ||
