So, if something cycles through five wavelengths in a single second, we would just say that the frequency of that wave is five per second.
如果一个东西在一秒,内经历了五个波长,我们就说这个波的,频率是每秒5次。
So, we should be able to look at different types of waves and be able to figure out something about both their frequency and their wavelength and know the relationship between the two.
我们可以看到,不同的波并从它们的,波长和频率中,获得一些信息,我们知道。
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。
So, it's up on this screen here now, so we'll work on the other one. If you can identify which of these statements is correct based on what you know about the relationship between frequency and wavelength and also just looking at the waves.
它们之间的关系,现在在大屏幕上了,鉴于你们知道,频率和波长的关系,看到这些波你们来,判断下这些说法是否正确。
