The speed of light will be minimum while passing through which of the following mediums? Notes: Light travels at approximately 300,000 kilometers per second in a vacuum, which has a refractive index of 1.0, but it slows down to 225,000 kilometers per second in water and 200,000 kilometers per second in glass.
A. inductance
B. voltage
C. capacitance
D. None of these
Farad, unit of electrical capacitance (ability to hold an electric charge), in the metre–kilogram–second system of physical units, named in honour of the English scientist Michael Faraday. The capacitance of a capacitor is one farad when one coulomb of electricity changes the potential between the plates by one volt.
