When placed in a beaker of water and exposed to sunlight , silicon absorbs photons of sunlight , generating electrons with enough energy to conduct through the silicon .
当把叶子放入烧杯中,置于阳光下的时候,硅吸收了阳光中的光量子,产生了有足够能量能够穿过硅层的电子。
As before , they use polarized x-ray photons to excite iron-57 nuclei immersed in a magnetic field .
和以前一样,他们也利用极化的x光射线去激发处于磁场中的铁-57原子。
To test the connection between photons and fat , scientists took mice and lit up their cages .
为证明光和脂肪之间的联系,科学家在小鼠身上做了个实验。
An x-ray detector would then pick up the x-ray signal of these photons .
那么,x射线探测器将会捕捉到这些光子散发的x射线信号。
When photons pass through or reflect off of something , they give that object momentum .
当光子穿过或者反射到某物体上时,物体就会有动量产生。
Most photovoltaic cells , such as those used in rooftop solar panels , use the semiconducting material silicon to convert the energy from photons of light to electricity .
