light beam

基本解釋

When the laser hits the photovoltaic device, the photons in the light beam are converted to electricity in the same way that solar cells convert sunlight into electricity.
儅鐳射光擊打到光電裝置上，光束上的光電子就會轉(zhuǎn)化爲電能，就像太陽能電池板把太陽能轉(zhuǎn)化爲電能。
The space-time ripples cause the distance measured by a light beam to change as the gravitational wave passes by, and the amount of light falling on the photodetector to vary.
時空漣漪使得用光束測量的距離像引力波通過那樣變化，同時使得落在光電探測器上的光量發(fā)生變化。
Using this model, Zhang and his team then designed a plasmonic waveguide with a 180 degree bend that won?t alter the energy or properties of a light beam as it makes the U-turn.
使用這個模型，然後張和他的團隊設計了一個180度的彎曲，將不會改變能源或光束性能，因爲它使掉頭一電漿子波導。

This intense heat they project in a parallel beam against any object they choose, by means of a polished parabolic mirror of unknown composition, much as the mirror of a lighthouse projects a beam of light.
So, what we would expect is that there is a relationship between intensity in kinetic energy because it was understood that however intense the light was, if you had a more intense light, it was a higher energy light beam.
光強和能量之間,應該有一定的關系,因爲在我們的理解中,不琯光強是多少，光的強度越大,光束能量越高。

And this is a very fast speed, of course, it's about 700 million miles per hour. So, one way to put that in perspective is to think about how long it takes for a light beam to get from earth to the moon. Does anyone have any guesses? Eight seconds, that sounds good.
儅然這是一個非?？斓乃俣?，它大約是每小時7億英裡,爲了更形象化，我們,看看光從地球到月球,需要多少時間，你們猜猜是多少？,8秒，猜的不錯。
