Quick video on how to calculate for either the frequency or wavelength of light using the speed of light equation. Finally calculate the index of refraction. The basic concept behind both events involves the speed of light and all other forms of electromagnetic radiation which scientists have thoroughly examined and is now expressed as a constant value denoted in equations by the symbol cNot truly a constant but rather the maximum speed in a vacuum the speed of light which is almost 300000 kilometers per second can be manipulated by.
For example the speed of light through water is 22500000 kms.
In a fluid at rest the wave speed of a fluid is equivalent to the speed of sound in the same medium whether liquid or gas. Therefore the refractive index of a medium may also be defined as the ratio of the speed of. Watts Volts Amps or WVA in short. The first successful measurement of the speed of light took place in 1676.
