So here we say the speed of light is the product of wavelength and frequency. And in a vacuum it travels at a speed of 3.00 times 10 to the 8 meters per second. And we're going to say here, it is a physical constant and uses the variable c. So we know that c now represents the speed of light, and with it we have our speed of light formula. Here, c our speed of light equals wavelength, which we said was lambda times our frequency, which we said was mu. So here we're going to say, remember frequency uses and wavelength uses Lambda, and remember frequency is in units of seconds inverse, which is equivalent or equal to hertz, and that wavelength is in units of meters. Remember, it's in this in these units, so that it matches the units of our speed of light. Now that we know how wavelength and frequency are connected to the speed of light, move on to the next video and take a look at the example question.
