Hi there.
00:02
In this question, we are given a wavelength and we want to know the frequency.
00:06
Well, to do that then, we need to use the equation that tells us that wavelength times frequency for any members of the electromagnetic spectrum.
00:15
So, in other words, light, is equal to the speed of light in a vacuum, which is 3 .0 times 10 to the 8 meters per second.
00:27
All right.
00:28
So we notice that in speed of light, there is meters.
00:30
So when we rearrange this equation to solve for frequency by dividing both sides by wavelength, we get 3 .0 times 10 to the 8th meters per second over wavelength.

Well, in order to divide these, wavelength is going to need to be in meters...
