So here we're consigning ourselves with the formula of the energy levels.
00:04
So what we know is that ei is equal to negative rh over 25.
00:11
Ef is equal to negative rh over 4.
00:15
While rh is the constant, that is 2 .179 times 10 to the negative 18 joules, where ei take away ef is equal to hmu, hv, sorry, where hv is equal to 21rh divided by 100.
00:40
Where h is the planet's constant, we have 6 .626 times 10 to the negative 34 joules per second, and v is the frequency, where we solve for v that is equal to 21rh divided by 100h.
00:57
So we can plug our numbers in to get the frequency to equal to.
01:02
To 21, multiplied by 2 .179 times 10 to the minus 18 joules...
