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。

And the reason that quantum mechanics is going to work where classical mechanics fails is that classical mechanics did not take into account the fact that matter has both wave-like and particle-like properties, and light has both wave-like and particle-like properties.

上发生的行为,量子力学得以成功,而经典力学却失败的原因,是因为经典力学,不能包容物质的，波动性和粒子性,和光的波动性和粒子性。

This is especially useful in low-light situations like party shots, indoors or dusk where built-in flashes have historically struggled to reach far-away subjects and capture all important details of a scene.

In a process similar to printing a photograph, engineers beam high-powered light through a mask-like image of the chip, creating a duplicate on a silicon wafer.

FORBES: Trick of the Light

Terahertz light - which lies between infrared light like that used by remote controls and the microwaves in the appliance of the same name - has become popular in scanning technology at airports and museums' back rooms because it can extract information without risk of damage.
