Light has the properties of a wave and a particle. The word “wavelength” is used to express the wave or undulating property of light. It is the distance that light travels in one oscillation, and is often expressed using a unit called "nanometer". One nanometer is equal to one billionth of a meter. Our eyes can only see light that is of a wavelength between approximately 400 to 700 nanometers. This range is called the visible light. The light of other wavelengths includes X-rays, ultraviolet rays, and infrared rays. Though we cannot see them directly, these are also members of the light family.
On the other hand, light also has the property of a particle. The intensity of the light varies depending on the number of particles. Bright light has many particles while dark light has fewer particles. These particles of light are called “photons”.
