electrons
a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
frequency (light)
Light is measured by its wavelength (in nanometers) or frequency (in Hertz). One wavelength. equals the distance between two successive wave crests or troughs. Frequency (Hertz) equals the number of waves that passes a given point per second.

wave length (light)
Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. ... 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).
