Meaning of Light

What is Light:

Light is electromagnetic radiation and we generally refer to that which is visible to us. Light is transmitted in the form of waves whose reflection illuminates the surfaces, thus allowing us to see the objects and colors around us.

The colors that the human eye can distinguish fall within what is called the visible spectrum of light.

In this sense, light is manifested by wavelengths, at the end of the longest waves we have the type of radiation like radio waves, and at the end of the shortest waves are gamma rays. Both ends of the spectrum are invisible to human vision.

The ways in which light propagates are defined in what is known as the electromagnetic spectrum. Visible light is somewhere between infrared light and ultraviolet light.

As a source of light we refer to everything that originates energy, whether in visible or invisible terms, such as:

  • the sun produces light in the form of light energy, within the electromagnetic spectrum that lies between visible light and ultraviolet light,
  • power supplies that generate electric light with energy-efficient and energy-saving technologies such as LED lights, and
  • the so-called spiritual sources that give the faithful spiritual light or divine light.

Properties of light

The properties of light are constantly studied, especially in physics and in the theory of colors, which answers questions such as are black and white colors?

The study of the properties of light was only possible thanks to the Newton prism, which later creates the basis for the study of optics. Isaac Newton (1643-1727) presents his research on the interaction of light with other materials in his work Optics from 1704.

Some of the most important properties define that light:

  • spreads in a straight line,
  • An incident ray is defined as that which reaches a surface,
  • is defined as reflected lightning when bouncing off a reflective surface,
  • changes direction when refracting from one surface to another,
  • allows the human eye to see shapes and colors.
