How is light measured

WebLight is electromagnetic radiation which is visible to the human eye.Electromagnetic radiation is generated by the oscillation or acceleration of electrons or other electrically charged particles. The energy produced by this vibration travels in the form of electromagnetic waves. WebEnergy at individual wavelength or over a range of wavelength can be measured. Another area of interest is color. Color is a property of light and can be measured and quantified. The science of light measurement is known as photometry and is a subset of the broader field of radiometry – the measurement of radiation outside the visible spectrum.
