What is the nature of light? Particle or wave? How fast is light speed? These are all basic questions of physics.

光的本质是粒子还是波？光速是多快？这些都是物理学的基本问题。

When a light particle,or photon, hits an electron, the electron jumps to a higher energy state.

What we had just done a clicker question on is discussing light as a particle and the photoelectric effect, so we're going to finish up with a few points about the photoelectric effect today.

我们刚才做得课堂表决器那个问题,是讨论光作为一个粒子以及光电效应，所以今天我们将以一些,关于光电效应的观点作为结束。

So, it turns out that the photoelectric effect is not the only evidence for the fact that light has these particle-like characteristics.

所以，原来是光电效应,不是唯一的证明光具有,粒子特性的证据。

The decision of whether or not to observe a light particle affects how the light behaves beforehand.

Composed of light-absorbing, colloidal quantum dots linked to carbon-based fullerene nanoparticles, these tiny two-particle systems can convert light to electricity in a precisely controlled way.

This shows that light is actually neither just a particle nor just a wave, but rather both simultaneously.
