So, similarly in a case where instead we have a small energy difference, we're going to have a low frequency, which means that we're going to have a long wavelength here.

在这个例子里,能量差较小,我们得到的频率低,这意味这它的波长更长。

In the real world, no one's going to measure it instantaneously, but we can make the difference as small as we like.

在现实生活中,没人能一瞬间测出来,但我们可以使差值越来越小
