as far as i know, when plugged in, SLM 's change index of refraction to accommodate the phase changes happening to the input (light). Is there a range for the possible values of the index of refraction?
The index of refraction is a measure of how much a material bends light as it passes through it, compared to the speed of light in a vacuum.
The range of values for the index of refraction varies depending on the material. For example, air has an index of refraction of approximately 1, while diamond has an index of refraction of 2.42.
The index of refraction is calculated by dividing the speed of light in a vacuum by the speed of light in the given material. This calculation is typically denoted by the letter "n".
The higher the index of refraction, the slower light travels through a material. This is because the particles in the material cause the light to bend and take a longer path through the material.
The index of refraction is important in many applications, including designing lenses for glasses and cameras, creating optical fibers for telecommunication, and studying the chemical composition of various materials using spectroscopy.
