The simplest definition of light is “visually perceived radiant energy". “Visible” light is just a small segment of the electromagnetic spectrum— a broad range of radiant energy which also includes X-rays, ultraviolet and infrared energy, micro-waves and radio waves.

Rectilinear propagation describes the tendency of Electromagnetic waves (light) to travel in a straight line. Light only deviates from a straight line when the medium it is travelling through changes density. This is called refraction.

Explanation:

Light is a form of electromagnetic radiation emitted by hot objects like lasers, bulbs, and the sun. Light is a kind of kinetic energy Which enables the human eye to see or make things visible.

The rectilinear propagation of light means that light travels in straight lines as a wave. ... In a pinhole camera, the light rays reflecting from the bottom of the object travel in a straight line through the pinhole to the film.
