Well we owe it to the photoelectric effect.

这要归功于应。

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

1839 年，法国物理学家埃德蒙·贝克勒尔首次观察到应。

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应观测结果。

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

因此，诺贝尔奖被授予阿尔伯特·爱因斯坦，以表彰他发现应。

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

强度高并不意味着它就会引起应。

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

他们发明出吸收太阳池以及生成分解剂。

These diverse applications all stem from the photoelectric effect.

这些不同应用都源于应。

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

简单地说，应是一种照射金属，导致子脱落现象。

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

例如，阿尔伯特·爱因斯坦主要是因为应研究而获得了诺贝尔物理学奖。

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

这首次解释了所谓应。

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

让我给你展示一下应是如何工作。

The photoelectric effect works in a similar way.

应也以类似方式起作用。

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

好吧，科学家们像阿尔伯特·爱因斯坦就能分析应结果。

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

应在现实世界中有许多实际用途，其中最重要是太阳能发。

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

在学习应时，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应如何证明作为粒子性质。

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，而是因为应。

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

烟雾探测器在一个腔室一侧有一个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.

而且应显示，可以表现为粒子，或者它以粒子形式作用。

And so what is the photoelectric effect?

什么是应？
