For this problem, we're given information about a carbon -oxygen double bond in an organic molecule that is able to absorb radiation with a frequency of 6 .0 times 10 to the 13th per second.
00:15
And the first part we're being asked to do is figure out what is the wavelength.
00:19
So we're going to use wavelength equals the speed of light divided by frequency.
00:27
And if we go ahead and substitute in here, so the speed of light is 3 .0 times 6 .5.
00:32
10 to the 8th divided by our frequency, which is 6 .0 times 10 to the 13th.
00:40
And so we get that our wavelength is going to equal 5 times 10 to the negative 6 meters, because our speed of light is in meters.
00:59
And so that is going to equal 5 ,000 nanometers.
01:07
Now, part b of this question is asking the 5 ,000 nanometers, it's asking what region of the spectrum that radiation belongs to.
01:20
So if we look at our electromagnetic spectrum, we're going to see that 5 ,000 is going to be in here in the infrared portion of the spectrum...
