blacklight是什么?难道食堂里杀虫的荧光灯就是blacklight? 英语
网友回答
【答案】 Black light (also Wood's light) is the mon name for a lamp emitting electromagnetic radiation that is almost exclusively in the soft near ultraviolet range,and very little visible light.In many areas this type of lighting is more monly referred to as simply UV light.
那个杀虫的荧光灯既然你看得到它在发光,说明就不是blacklight.不可见光意思是这种光你看不见,你用肉眼看不见他的光.弱国这个物体只发出blacklight,你看到他就是黑色的.像紫外线,你是看不见的.
