Why Doesn't UV Light Kill All of the Bacterial Cells? 1

1. For a turtle can u just use a lamp instead of a uv light?

Aquatic turtles need both a basking light and a UV light, without the UV light they do not get all the calcium they need and it can give them metabolic bone disease. A basking light is for them to sun them selfs without the sun. As far as aquatic turtles go to exotic pets it has different types of them, but when you go to the pet store just tell them that you are interested in an aquatic turtle and they will show you what they have as they can also be called water turtles as my sons use to always call them.

2. What are some common household substances or items that glow under UV light?

Laundry detergent has added fluorescent dye to make clothes look whiter in sunlight,which does have UV in it Some white clothes also have it, check them under a black light Clothes worn at night for people working outside have strips that glow.

3. Does neon urine signal a vitamin overdose?

Getting too much Vitamin B 12 might be a slight expense, but it's not a health concern. Several people have told me this is a signal that I am taking too many vitamins and, as a result, producing "really expensive urine." So, are they right? And do I need to be worried? Neon yellow. That's the color of my urine after I take my daily vitamins. Some have said that the eyes are the windows to the soul. A lesser-known (and less poetic) corollary is that urine is a window to your diet and health. For you, the bright yellow color of your urine is almost certainly attributable to excess vitamin B2. The RDA (Recommended Dietary Allowance) for riboflavin is about 1 milligram a day. But vitamins can contain many times that amount, especially if you take a vitamin B supplement. And because riboflavin and other B vitamins are water-soluble, your body dissolves any excess and excretes it in - you guessed it - your urine. So, the fact that your urine looks like a highlighter does, indeed, mean you are taking in more riboflavin than you need. But it's a no-harm, no-foul situation, as your body has a ready mechanism for draining the overflow. As a result, you need not worry about excess amounts lingering in your system.

4. Why does snow reflect so much UV light?

Because it is white

5. My boyfriends semen does not glow in UV light (black light)?

lmao do not believe what u see in CSI

6. Is there any chance for UV light to get converted into visible light due to the Doppler effect in outer space?

Oh No. You have not understood the concept of Doppler effect well. It's OK, have no worries, here.Doppler effect totally works on relative speeds. When you see the red shift or the blue shift in the spectrum, the waves are not actually changing their wavelengths. Imagine it like this. Let's say you are beside a road and a series of only cars are going, for every 5 minutes. Whatever their speeds, we are not to worry about that. Concentrate on the interval between them. Every 5 minutes. Now, you start moving against them in the footpath with some constant speed. You count the interval but the cars are taking less time than before,
