don't florescent lights give of ultraviolet lights? if so then why do we have the ability to visualize and and why wouldn't it be considered visible light?

what about incandescent light bulbs, halogen lights and LED lights? are they all considered visible light?

If turning on the light allows you to see stuff then it is producing visible light. That does not mean that it produces ONLY visible light, it may also be producing infrared or ultraviolet radiation.

Light sources produce a range of wavelengths. If fluorescent lights do not produce visible light then how can you see the light? How can you read a book with fluorescent lighting. Of course there is light. UV light is also produced by light sources but we cannot see them because humans never adapted to see ultraviolet light. Light is just waves of different wavelengths. We can only see a certain range. A light source can produce ranges which we can see and cannot see at the same time.

i would say no. because florescent light is when you pass electrical currents through gas, which causes the electrons to "leap"out. i dont think the light is a part of the visible light spectrum. so no

If you turn it on in darkness and produces light, then the answer would be yes.

they give off ultravolit rays some say lights but there are rays thats why we dont condider them visible light
