Hi there.
00:03
In this question, we are given the frequency of a light wave, and we want to determine its wavelength.
00:10
So to do that, we need the equation that says wavelength.
00:13
So this is for anything that's on the electromagnetic spectrum, the wavelength times the frequency equals c.
00:21
And c is the speed of light.
00:24
So if we want to solve for wavelength, i'm going to rearrange this by dividing both sides by frequency.
00:31
Wavelength is going to be the speed of light divided by that frequency that we have here.
00:38
So let's go ahead and calculate this.
00:40
So the wavelength is going to be speed of light is 3 .00 times 10 to the 8 meters per second.
00:51
Actually, i'm going to write it as meters per second with a negative 1.
00:58
And then our frequency that we're given in the problem is 4 .60 times 10...
