If you do it the other way, it becomes a stylus tip and in another way, it becomes a laser pointer.

如果你以另一种方式转动它，它就变成一支触控笔，再换一种方式转动，它就变成一支激光笔。

Since we have my red laser pointer, we will also try with the red laser pointer, which is centered at wavelength of 700 nanometers.

因为我们有我的红色激光笔，我们也会尝试红色激光笔，它的中心波长是 700 纳米。

So we see that we do not eject electrons in the case of the laser pointer, even if we have this intensity, it is still not related to the energy of an individual photon, so we won't see an effect.

所以我们看到我们用激光笔,还是没有逐出电子，即使我们有这样的强度，它仍然与一个单个的光子能量无关,所以我们不会看到光电效应。
