what is the difference between illuminant and source of light? What is the unit of illuminance and how can we calculate illuminance for IR light source?
An illuminant is a physical object that emits light, while a source of light is a concept used to describe the origin of the light.
Examples of illuminants include the sun, light bulbs, candles, and fires.
The type of light emitted by an illuminant can affect the color of an object by influencing the wavelengths of light that are absorbed or reflected by the object's surface.
Our perception of color is influenced by the type of light source illuminating an object. Different sources of light emit varying combinations of wavelengths, which can make an object appear to be a different color under different lighting conditions.
Understanding the difference between illuminants and sources of light is crucial in scientific fields such as color science and vision science. It allows researchers to accurately measure and describe the properties of light and how it affects our perception of color.
