And sure enough, increasing the intensity of the light only affects the number of electrons ejected.

当然，增加光的强度只会影响移除的电子数量。

Is there a cutoff frequency below which electrons aren't ejected from the metal, no matter how long you wait?

是否有一个截止电压，无论您等待多长时间，都不会从板中提取电子？

And when you increase the intensity of the light, does that affect the maximum kinetic energy of the ejected electrons?

而当光的强度增加时，这会影响被移除电子的最大动能吗？
