Ultraviolet (UV) light can help visualize germs because many microorganisms, including bacteria and viruses, fluoresce when exposed to UV light. Certain dyes or stains can be applied to the surface or medium containing the germs, making them emit visible light under UV illumination. This property allows for the identification and observation of germs that are otherwise invisible to the naked eye. However, it's important to note that while UV light can highlight the presence of germs, it does not provide information about their viability or specific types.
What else can I help you with?
Can ultra-violet light kill germs?
No, but if you put on a cream you can see them.
What are some objects that reflect light?
Everything that you can see reflects light to some degree (that is how you see it). Just because you can't see something though doesn't mean it doesn't reflect light. It may be the object is too small or reflects too little light for you to see it, or that it reflects light not visible to the human eye (like infra-red or ultra-violet)
What are you actually seeing when you see an object?
What you see is really just the reflected light with a frequency between about 400 to 800 nanometers (10^-9 m), aka violet through red.
What tools does a forensic scientist use?
Forensic scientists use a lot of computer technology, microscopes, and they draw what they see a lot. They also use kits for discovering finger prints, ultra violet lights or blacklights to see unknown substances on a scene (semen, saliva, blood)
Why can't you see germs?
because they are too small
Can ultra-violet light kill germs?
No, but if you put on a cream you can see them.
What is the comparison between visible light and ultra violet light?
You can see visible light but not ultra violet light.
Do dogs and cats see things in ultra violet light?
yes in fact cats and dogs do see things in ultraviolet lightm if you are wondering what ultra violet light is it is form of radiation whitch is not visible to the human eye
When there are white stains in your car how can you check to see if its semen?
ultra violet light will show if its bodily fluids
Can any bird see both ultra violet and infra red light?
no sorry if that is not enof info
Can the honey bee see ultraviolet light?
A honey bee's colour vision extends well into the ultra violet range of the spectrum so thay can see ultra violet light.
Why is the human eye unable to see ultraviolet light?
You should look at it the other way round. The word 'ultra' means 'beyond', so you have the visible spectrum which ends at violet, then what is beyond is 'ultra violet'.
Can birds see ultra violet?
some can
Which animal can see in ultra violet?
Bat
What attracts bees to dandelions?
Bees can see UV light. (ultra violet light), that we, humans can't see. So, actually any flower attracts bees.
What kind of radiation does a bee see?
A bee's eye has receptors for green, blue and ultra-violet, so they can see in ultra-violet, which we can't, and we can see red, which they can't.
Can mosquitoes see in red light?
Bees have three types of colour receptor in their eyes, and their color sensitivities peak in the yellow-green, blue, and ultra-violet regions of the spectrum. This means that bees can see ultra-violet (which we can't), and the yellow-green receptors peak further up the spectrum that our own red-orange receptors. However, the receptors also pick up colours either side of their peak sensitivity, so it is likely that a strong enough red light will be detected, but will not be seen as well as we can see it.
