Now I have lambdas associated with transitions between energy levels in atomic hydrogen.
现在我把波长和,氢原子中的,能级跃迁联系起来。
So, what we know is happening is that were having transitions from some excited states to a more relaxed lower, more stable state in the hydrogen atom.
我们知道,这里所发生的是,氢原子从激发态到更低更稳定的态的跃迁,而我们用眼睛可以探测到的。
Gee, I wonder if I could come up with a set of transitions occurring inside atomic hydrogen Just right match that what Angstrom measured back in 1853.
嘿!我想知道我是否可以想出,发生在氢原子内的,一系列的跃迁,正好符合,阿姆斯特朗在1853年测得的东西。
So this means that we can go directly from the energy between two levels to the frequency of the photon that's emitted when you go between those levels.
这意味着我们可以直接,从两个能级的能量得到它们之间,跃迁发射出光子的频率。
And what we predict as an energy difference between two levels, we know should correspond to the energy of light that's either emitted, if we're giving off a photon, or that's absorbed if we're going to take on a photon and jump from a lower to a higher energy level.
我们预测,两个能级之间的能量差,我们知道,它要么和发出的光有关,如果它发出光子的话,要么它吸收光子,从低能级跃迁到,更高能级上去。
We saw a similar thing as we saw electrons move from different levels.
这与我们曾经见过的,不同能级之间的跃迁很类似。
We're getting further away from the nucleus because we're jumping, for example, from the n equals 2 to the n equals 3 shell, or from the n equals 3 to the n equals 4 shell.
我们将会离原子核越来越远,因为我们在跃迁,比如从,n,等于,2,的壳层到n等于,3,的壳层,或者从,n,等于,3,的壳层到n等于,4,的壳层。
p So to jump from the 2 s to the 2 p, takes more energy than we can actually compensate with by increasing the pull from the nucleus.
也就是,从,2,s,跃迁到,消耗的能量超过了,由于原子核的引力增强而补偿的能量。
