Alright, so in this video again, we're going to be exploring how a lot of general chemistry is just a lot of hidden math and how to calculate things.
00:11
We're going to be using this frequency to a wavelength conversion equation right now.
00:20
So we're going to use the speed of light, which is c, right at the top, 10 to the 8th, and divide that by our wavelength.
00:31
Our wavelength is given in nanometers, which is why i'm multiplied by 10 to the negative 9th, which is the same thing as dividing by a billion because there's a billion nanometers in every meter.
00:46
You can also just write in just so you know the way the speed of light is in meters per second versus the wavelength is given in meters.
01:01
And that's going to be giving you 6 .379 times 10 to the 14th.
01:09
Which will be in seconds to minus one.
01:16
Next thing we're going to do is we're going to use this equation, which is e equals hv, right, to find our energy for one photon.
01:32
So we're going to be using planck's consonant, which is 6 .6 -26 times 10 to negative 34.
01:38
We're going to multiply that by our frequency that we just found...
