So let's do a sample calculation now using this Rydberg formula, and we'll switch back to emission, and the reason that we'll do that is because it would be nice to actually approve what we just saw here and calculate the frequency of one of our lines in the wavelength of one of the lines we saw.
讓我們用Rydberg公式,做一個例題，我們廻到發射上,這麽做是因爲這樣,可以用我們看到的波長,來騐証我們計算的頻率。
