Right, so in this problem, we're given wavelength, and we need to find the transition states, the final end initial transition states.
00:09
So the first thing we can do is find frequency.
00:13
We know the frequency is equal to speed of light, which is 3 times 10 to the 8 meters a second, divided by wavelength, which they gave us as 1 to 8 to the 0 times 10 to the negative 9 meters.
00:36
Which gives us a frequency of 2 .34 times 10 to the 14th hertz.
00:50
We can go ahead and plug this into another equation in your book, which says the frequency is equal to place constant, 6 .63 times 10 to the negative 34th, and this is under 2 .1 .8 times 10 to the negative 18th joules.

And plank's constant.
01:23
We know it's joules per second...
