A beam of light coming from the projector in a cinema hall suggests that light travels in a straight line. The path along which light travels in a given direction is called ray of light. Hence we say, light travels in a straight line. This property of light is called rectilinear propagation of light. Ray of light is shown as a straight line with an arrow on it.
