00:00:01.000 --> 00:00:06.919
ultraviolet kind of sounds like the name of a metal band but most of us know it

00:00:04.960 --> 00:00:11.440
primarily as that stuff from the Sun that makes you look like a lobster if

00:00:08.559 --> 00:00:16.359
you spend too much time at the beach but even though ultraviolet or UV light is

00:00:14.080 --> 00:00:22.279
the scourge of vacationers the world over there are plenty of awesome things

00:00:19.560 --> 00:00:27.279
that it can do as well and I'm not just talking about tanning beds but what

00:00:24.519 --> 00:00:30.480
makes it so useful well UV light like regular light is a form of

00:00:28.800 --> 00:00:34.879
electromagnetic radiation which moves through space in waves but

00:00:32.880 --> 00:00:40.520
ultraviolet waves have a shorter wave length and a higher frequency than

00:00:37.320 --> 00:00:43.559
visible light hence the name ultraviolet

00:00:40.520 --> 00:00:46.000
as UV light has a higher frequency than

00:00:43.559 --> 00:00:50.719
violet light which has the shortest wave length of any visible color higher

00:00:48.559 --> 00:00:55.760
frequencies mean higher energy meaning UV light has lots of effects that

00:00:52.800 --> 00:01:00.000
regular light just well doesn't for example sunburns happen because UV light

00:00:57.680 --> 00:01:05.000
from the sun has enough energy to Dam damage the DNA in your skin the

00:01:02.840 --> 00:01:10.960
subsequent burn and sensitivity are part of your body's attempt to repair your

00:01:07.479 --> 00:01:13.439
DNA and shed heavily damaged skin cells

00:01:10.960 --> 00:01:19.280
but if you're exposed to a lower level of UV light this will trigger your body

00:01:16.040 --> 00:01:21.759
to release more melanin which absorbs UV

00:01:19.280 --> 00:01:26.799
light before it can damage your skin this results in a suntan making UV rays

00:01:24.920 --> 00:01:32.360
crucial if your goal in life is to look like Cristiano Ronaldo or Snookie EXP

00:01:29.920 --> 00:01:37.680
exposure to small amounts of UV can also actually have benefits as it causes your

00:01:34.479 --> 00:01:39.360
body to make more vitamin D but uv's

00:01:37.680 --> 00:01:44.439
High energies have plenty of applications even if you don't spend all

00:01:41.600 --> 00:01:49.719
of your time outside artificial UV light bulbs use the same DNA damage effect to

00:01:47.439 --> 00:01:55.040
kill bacteria meaning you can find them everywhere from water treatment plants

00:01:52.200 --> 00:02:00.680
to bathrooms where people keep their toothbrushes under a UV lamp and

00:01:57.840 --> 00:02:05.399
speaking of gross stuff under a UV lamp UV Tech is also used in black lights

00:02:02.880 --> 00:02:09.959
that are used to reveal stains molecules that make up proteins can absorb UV

00:02:07.600 --> 00:02:16.519
light allowing them to contrast with the background enabling you to see things

00:02:12.480 --> 00:02:20.319
like blood stains pet urine stains and

00:02:16.519 --> 00:02:23.040
other questionable fluids in fact some

00:02:20.319 --> 00:02:27.720
companies even make travel siiz UV lamps so you can you know see whether

00:02:25.400 --> 00:02:32.680
housekeeping at your hotel has missed anything higher powerered UV bul are

00:02:30.319 --> 00:02:38.040
used by police even when investigating crime scenes for the same reason and

00:02:35.480 --> 00:02:42.840
because UV is indeed a form of light some kinds of animals can see it even

00:02:40.239 --> 00:02:48.000
though we unfortunately can't including insects like house flies which are drawn

00:02:45.000 --> 00:02:50.159
to UV light making UV bulbs a popular

00:02:48.000 --> 00:02:55.599
feature in bug zappers but if you're more interested in electronics that are

00:02:52.480 --> 00:02:57.200
a little bit more high tech UV is used

00:02:55.599 --> 00:03:02.720
in a process called photolithography where UV light helps to

00:02:59.840 --> 00:03:07.920
form patterns on Silicon Wafers that CPUs are made from you can learn more

00:03:05.159 --> 00:03:12.440
about this in this video we're also seeing UV light used more and more in

00:03:09.920 --> 00:03:18.000
the world of identity security as things like ID and credit cards are printed

00:03:14.959 --> 00:03:20.120
with patterns that only react under UV

00:03:18.000 --> 00:03:25.360
light which are quite difficult to forge or counterfeit no word yet on whether

00:03:22.560 --> 00:03:30.840
we'll see UV authentication on Pokémon cards however tow CLE or a clean system

00:03:28.239 --> 00:03:35.799
ships with one toothbrush three clean brush heads a base station and a charger

00:03:33.959 --> 00:03:41.560
and the claim that it is the cleanest toothbrush in the worlds it has two

00:03:38.720 --> 00:03:46.120
speed modes to deliver up to 40,000 Strokes per minute much better than just

00:03:44.000 --> 00:03:50.959
your hand and it even removes things like plaque and delivers a superior

00:03:48.680 --> 00:03:56.000
clean that's all bundled with a 2-minute timer for brushing time with interval

00:03:52.959 --> 00:03:58.599
alerts for when to change brushing zones

00:03:56.000 --> 00:04:03.959
the station also contains a UVC light that eliminates 99 99.9% of bacteria and

00:04:02.079 --> 00:04:08.439
keeping the brush handle on the base station ensures that it's protected

00:04:06.000 --> 00:04:13.000
while also drying the brush charging it and well cleaning it the stylistic

00:04:10.840 --> 00:04:17.680
design and choice of two colors either black or white mean that it can go along

00:04:15.439 --> 00:04:20.040
with your elegantly designed bathroom if that's your thing if you want to see
