N a radio-frequency band or radio frequency lying between 3 and 30 megahertz 高频 ( abbr: HF)
You can't hear waves of such a high frequency.
你听不到这么高频率的声波。
Pay attention to the high frequency words and their associated forms.
注意高频词及其关联形式。
For example, the high frequency word "rain" is very common and can be found in a number of important expressions.
例如,高频词“rain”很常见,可以在一些重要表达中找到。
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。
Maybe you can put the frequency of the higher pitches as high so you can detect the sound quicker and That's it exactly.
大概是把频率调到更高的音高后,就能更敏捷地感觉到声音的变化,而那就是原因了
So that should mean that the energy that's transferred to the electron should be greater, but that's not what you saw at all, and what you saw is that if you kept the frequency constant there was absolutely no change in the kinetic energy of the electrons, no matter how high up you had the intensity of the light go.
所以这意味着转移到电子,上的能量也越大,但这并不是,我们观测到的现象,我们所看到的是,如果固定光的频率不变,不管光强如何变化,电子的动能没有任何变化。
