390nm ~800nm wavelength among the lights is called visible lights area that we recognize as a light. Out of rainbow colors like purple, navy blue, blue, green, yellow, orange, and red, yellowish green which is located at 555nm from these visible lights is known as the brightest one.

Visible light consist of different types of colors. These colors are differentiated on the basis of their wavelengths in the visible spectrum. Visible Light Spectrum Chart is the breakdown of the colors present in the white light with respect to their wavelengths or frequencies. The Colors of Visible Light are Red, orange, yellow, green, and cyan, blue, violet.

According to the particle theory of light, light consists of particles called as photons. Energy of the visible light is given by the formulae:
E = hf
Where, E = Energy of the light waveh = Planck’s constantf = frequency of the wave
