红端 meaning in English

red end

The more the light is shifted to the red , the farther away the source is and thus the older it is
往红端偏移越多，代表它的源头距离我们越遥远，也就是年纪越大。
Because of the universe ' s expansion , the light from distant sources has been stretched , shifting its wavelength toward the red end of the spectrum
因为宇宙膨胀的缘故，来自远处的光会被拉长，因此波长将会往光谱的红端偏移。
If the star emitting the light is moving away from us , its light rays have a longer wavelength ( lower frequency ) by virtue of doppler principle and this is manifested in a general shift of the spectrum lines towards the red end of the spectrum
如果发某种光的恒星离开我们，根据多普勒原理，其光线的波长较长（即频率较低），在光谱上则显示出谱线全部移向红端。
