Short-wavelength, Tiny light spot, Small thermal effect, With obvious advantages when processing the heat sensitive materials.

波长短，聚焦炮点小，热效应小，加工对热源很敏感的材料时紫外激光具备明显的优势。

That is because such systems use high-frequency (and therefore short-wavelength) radio waves that readily bounce off small objects that they encounter.

因为该系统往往使用高频电波（所以波长较短），当遇到很小的物体时（ 译者注 ：波长短，频散很严重，导致探测深度浅。

FIRE FROM THE SKY: This false-color, short-wavelength infrared image of the Eyjafjallajokull volcano's smaller eruption in March shows the power ofthis glacier-covered volcano.

来自天空的火：这是一张3月的一次较小的艾雅法拉火山喷发的失真短波红外照片。 这展示了这个被掩盖在冰川之下的火山的力量。

At the moment, the earth-observation satellites which employ microwaves generally use short-wavelength radiation, because this provides more detailed images.

Researchers said that result doesn't rule out the possibility that short-wavelength light also could be an alerting stimulus in the afternoon.

NASA's Jet Propulsion Laboratory, in Pasadena, California, used short-wavelength microwaves in 1992 to reveal caravan trails leading to the lost city of Ubar in the Arabian peninsula.
