Light is simply a name for a range of electromagnetic radiation that can be detected by the human eye.
The term “vision statement” refers to an explanation, usually in written form, of what a person or business wants to be or get done at some later point in time. It identifies goals, providing direction to activities and motivating people to move forward. People often confuse it with the mission statement, which simply explains an individual or company’s purpose for existing and which is more present-based. Although people usually associate it with businesses or other groups, a single person also can write one, especially to orient academic or career choices. Constructing them is fairly easy if a person fills out a basic formula including a time frame, objective and method.

Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. The word usually refers to visible light, which is the visible spectrum that is visible to the human eye and is responsible for the sense of sight.[1] Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), or 4.00 × 10−7 to 7.00 × 10−7 m, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths).[2][3] This wavelength means a frequency range of roughly 430–750 terahertz (THz).
Vision is the special sense by which the qualities of an object (such as color, luminosity, shape, and size) constituting its appearance are perceived through a process in which light rays entering the eye are transformed by the retina into electrical signals that are transmitted to the brain via the optic nerve
