The formula for the velocity of a wave is v = c/n, with v being velocity of the wave, c being the speed of light, and n is what is going to make the velocity of the wave different. Understand the formula for the velocity of a wave with help from a tutor and teacher in this free video on education and physics.

Hi, my name is Samir Malik and I'm a tutor in the Austin area for Middle School and High School students. Today we're going to be discussing the formula for the velocity of a wave. The velocity of a wave, in a given uniform is given by v=c/n. V as a velocity of the wave and c is the speed of light which is pre-determined and n is the refracted index of a medium. So we know that c is the speed of light and it's pre-determined; but n is is what is going to make the velocity of the wave different. For example, the refractive index in water is going to be different than the refractive index in air. So the velocity of wave in water would be less than the velocity of wave in air. So this is the definition of a velocity of a wave and some, and the formula and some examples I have provided you with.
