Just remember that violet light is the end that actually has the shortest wavelength, which means that it also has, of course, the highest frequency.
只要记住,紫色光在末端,实际上,它有最短的波长,意味着它当然也有最高的频率。
A decreased frequency is equivalent to a longer, or redder, wavelength. This is gravitational redshift.
较低了的频率,相当于较长或较红的波长,这就是红移。
So really what we'll probably do is instead either give you the wavelength or the frequency and you'll go ahead and calculate the energy from there.
所以实际上我们可能的做法是,给你波长或者频率,然后你可以通过他们计算得到能量。

就知道了,所以这应该,不是问题,记住紫色光,最后一个,它的波长最短,也就意味着它的频率最高。

所以实际上我们可能的做法是,给你波长或者频率,然后你可以通过他们计算得到能量。
If we have a high frequency, what about the wavelength, long or short? All right. Good. So we should always be able to keep these relationships in mind.
如果频率高,那波长是长还是短?,好,不错,我们要记住这些关系,类似的。
