Well we owe it to the photoelectric effect.

这要归功于电效应。

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

1839 年，法国物理学家埃德蒙·贝克勒首次观察到电效应。

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

在那个时代，科学家们仍然无法理解电效应的观测结果。

And so that Nobel Prize was awarded to Albert Einstein for his discovery of the photoelectric effect.

因此，诺贝授予阿伯特·爱因斯坦，以表彰发现电效应。

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

的强度高并不意味着它就会引起电效应。

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

们发明出吸收太阳的电池以及生成氢气的分解剂。

These diverse applications all stem from the photoelectric effect.

这些不同的应用都源于电效应。

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

简单地说，电效应是一种照射金属，导致电子脱落的现象。

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

例如，阿伯特·爱因斯坦主要是因为电效应的研究而获得了诺贝物理学。

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

这首次解释了所谓的电效应。

And so let me show you how the photoelectric effect works.

让我给你展示一下电效应是如何工作的。

The photoelectric effect works in a similar way.

电效应也以类似的方式起作用。

Well scientists like Albert Einstein were able to analyze the results of the photoelectric effect.

好吧，科学家们像阿伯特·爱因斯坦就能分析电效应的结果。

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

电效应在现实世界中有许多实际用途，其中最重要的是太阳能发电。

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

在学习电效应时，你会经常遇到“功函数”这个术语。

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

我们还讨论了子以及电效应如何证明作为粒子的性质。

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，而是因为电效应。

Photoelectric smoke detectors have an LED on one side of a chamber and a sensor on the other side.

电烟雾探测器在一个腔室的一侧有一个LED，另一侧有一个传感器。

And so the photoelectric effect showed Albert Einstein that light is a particle or it acts as a particle.

而且电效应显示，可以表现为粒子，或者它以粒子的形式作用。

And so what is the photoelectric effect?

什么是电效应？
