Here we are going to explain how ultraviolet the intervals of the room are.
00:00:00
Enrique, Paloma, Sergio and me.
00:00:09
Here we go!
00:00:14
I am going to paint a notebook with a normal marker.
00:00:16
As you can see here, nothing happens.
00:00:29
But what if we light the fluorescent marker?
00:00:33
Wow! It's shining! But why does this happen?
00:00:43
For instance, a substance absorbs ultraviolet light and then sends it again instantly.
00:00:46
Some of the energy is lost in the process.
00:00:59
So the sent light has a longer wavelength than the absorbed radiation.
00:01:03
Making this light visible and making the material glowing.
00:01:08
so that's why the fluorescent marker glow bye
