So, most people could recognize that light wave a has the shorter wavelength. We can see that just by looking at the graph itself -- we can see certainly, this is shorter from maxima to maxima.
0秒钟,好的,不错大部分,同学都可以判断出来这个光波的,波长更短,我们仅通过,看图就能看出来-可以。
Alright. So, since we have these terms defined, we know the frequency and the wavelength, it turns out we can also think about the speed of the wave, and specifically of a light wave, and speed and is just equal to the distance that's traveled divided by the time the elapsed.
好了,我们已经定义了,这些术语,我们知道了,频率和波长,现在可以来考虑,波的速度了,特别是光波的速度,速度等于它走过的距离,除以所用的时间,因为我们。
And sometimes we model light as a wave.
有时候我们把光看成一种波。
They can't do something like wave goodbye or light a cigarette.
他们无法做到诸如挥手再见,或是点香烟这样的动作
So, we'll take a little bit of a step back after we introduce quantum mechanics, and talk about light as a wave, and the characteristic of waves, and then light as a particle. And one example of this is in the photoelectric effect.
等我们介绍完量子力学后,我们要回过头来讨论下光,作为一种波和它的波动性特征,以及光作为一种粒子,其中的一个粒子就是光电效应。
And the reason that quantum mechanics is going to work where classical mechanics fails is that classical mechanics did not take into account the fact that matter has both wave-like and particle-like properties, and light has both wave-like and particle-like properties.
上发生的行为,量子力学得以成功,而经典力学却失败的原因,是因为经典力学,不能包容物质的,波动性和粒子性,和光的波动性和粒子性。
