It isn't the Red Sea. That's a mistranslation that occurred very very early on, so it's led to the notion that they were at the Gulf of Aqaba or somewhere near the actual big ocean water.
并不是红海,这个错误的翻译很早以前就存在了,让人们以为是在亚喀巴湾,或者是接近真正意义的大洋的什么地方。
Also, what's the energy per photon of this red laser pointer, and then it's also worth trying a calculation dealing with intensity. So let's also try calculating the numbers of photons that would be emitted by this laser pointer, if, for example, we were to use it for 60 seconds and this were a one milliwatt laser.
同样,红色激光笔的,每个光子能量是多少,这也值得用处理强度的方法计算一下,让我们也计算一下,有多少光子会从这个激光笔射出,举个例子,如果我们使用它持续60秒,这里会有一毫瓦的激光。
