Ultraviolet light, or UV, is just beyond visible violet in the spectrum.
紫外线(UV)频率恰好在可见紫色光之外!VwAYE4r^5PVLPd
Its wavelength is too short to be visible to the naked eye, but you see it working when fluorescent colors glow!
紫外线的波长太短而肉眼无法看到,但是荧光色发光的时候你就能看到紫外线照射的效果!
Regular dyes just absorb UV along with all the other wavelengths they don’t reflect, so you don’t see any evidence of it.
一般的染料只吸收紫外线和所有其他不反射的光,因此你无法看到紫外线.VIxnJs^E)|vzV-NHt

But, fluorescent dyes contain substances that respond to UV.
但是,荧光染料含有对UV起反应的物质N0Hn(H2L-+OE
Some of the molecules in these fluorescent dyes are excited by UV energy, and afterwards, as the energy level within these molecules decreases, they release part of that extra energy as visible light.
这些荧光染料中的一些分子被UV的能量激活,然后,随着这些分子的能量水平下降,它们就会释放一部分额外的能量形成可见光*wj=J]~KkK0~3|B2]
So fluorescent dyes turn invisible energy into visible light, and that’s how the magic trick works!
因此,荧光染料把不可见的能量转换成了可见光,这就是魔术的原理!
They don’t reflect more energy than they receive, but they do reflect more visible light, converted from parts of the spectrum we can’t see.
它们并不是反射出所接收的额外能量,而是反射出了更多的可见光,这些可见光是由肉眼看不到的波段转换而来的8fGFT34t.(*;HdoecIKc
