These diverse applications all stem from the photoelectric effect.

这些不同应用都源于光电效应。

When learning about the photoelectric effect, you'll often come across the term " work function."

光电效应时，你会经常遇到“功函数”这术语。

The photoelectric effect works in a similar way.

光电效应也以类似方式起作用。

In 1839, French physicist Edmund Becquerel first observed the photoelectric effect.

1839 年，法国物理家埃德蒙·贝克勒尔首次观察到光电效应。

This was a time when scientists were still unable to understand the observations of the photoelectric effect.

那时代，科家们仍然无法理解光电效应观测结果。

Just because a light ray has a high intensity doesn't mean that it will cause the photoelectric effect.

光强度高并不意味着它就会引起光电效应。

Their work combines into a single unit the photoelectric cells that gather sunlight and the electrolyzer that produces hydrogen.

他们发明出吸太阳光光电池以及生成氢气分解剂。

Simply put, the photoelectric effect is a phenomenon in which light hits metal, resulting in the knocking off of electrons.

简单地说，光电效应是一种光照射金属，导致电子脱落现象。

That's the technical definition, but allow me to explain the photoelectric effect using an example of toll booths and traffic.

这是它物理定义，但请允许我用一站和交通例子来解释光电效应。

This explained what is known as the photoelectric effect for the first time.

这首次解释了所谓光电效应。

Einstein, for instance, won his primarily for his work on the photoelectric effect.

例如，爱因斯坦主要因其光电效应方面工作而获奖。

The photoelectric effect is used in solar power and various devices, such as photodetectors in cameras, burglar alarms, and industrial automation.

光电效应用于太阳能发电和各种设备，如照相机中光电探测器、防盗报警器和工业自动化。

The photoelectric effect has many practical uses in the real world, with the most significant being the generation of solar power.

光电效应现实世界中有许多实际用途，其中最重要是太阳能发电。

We also talked about photons, and how the photoelectric effect proves the particle nature of light.

我们还讨论了光子以及光电效应如何证明光作为粒子性质。

Despite this, Einstein did not win the Nobel Prize for relativity, but for the photoelectric effect.

尽管如此，爱因斯坦并没有因为相对论而获得诺贝尔奖，而是因为光电效应。

The photoelectric effect is where electrons are emitted when electromagnetic radiation, such as light, hits off a material or substance.

光电效应是当电磁辐射（例如光）撞击材料或物质时发射电子现象。

The results of all these tests with the photoelectric effect matchup with the predictions of the particle theory of light.

所有这些与光电效应有关测试结果都与粒子理论假设一致。

This photoelectric effect is easier to understand than relativity, so it took several decades for relativity to be gradually accepted.

这种光电效应比相对论更容易理解，因此相对论花了几十年时间才逐渐被接受。

But Einstein suggested a way to prove whether light traveled in these discrete packets: an experiment involving the photoelectric effect.

但是爱因斯坦提出了一种方法来证明光是否这些离散数据包中传播：一项涉及光电效应实验。

Let's fast forward another 100 years, to 1905. Scientists around this time had become puzzled by something known as the photoelectric  effect.

让我们再快进 100 年，到 1905 年。 此时科家对光电效应感到困惑。
