ultraviolet kind of sounds like the name of a metal band but most of us know it
primarily as that stuff from the Sun that makes you look like a lobster if
you spend too much time at the beach but even though ultraviolet or UV light is
the scourge of vacationers the world over there are plenty of awesome things
that it can do as well and I'm not just talking about tanning beds but what
makes it so useful well UV light like regular light is a form of
electromagnetic radiation which moves through space in waves but
ultraviolet waves have a shorter wave length and a higher frequency than
visible light hence the name ultraviolet
as UV light has a higher frequency than
violet light which has the shortest wave length of any visible color higher
frequencies mean higher energy meaning UV light has lots of effects that
regular light just well doesn't for example sunburns happen because UV light
from the sun has enough energy to Dam damage the DNA in your skin the
subsequent burn and sensitivity are part of your body's attempt to repair your
DNA and shed heavily damaged skin cells
but if you're exposed to a lower level of UV light this will trigger your body
to release more melanin which absorbs UV
light before it can damage your skin this results in a suntan making UV rays
crucial if your goal in life is to look like Cristiano Ronaldo or Snookie EXP
exposure to small amounts of UV can also actually have benefits as it causes your
body to make more vitamin D but uv's
High energies have plenty of applications even if you don't spend all
of your time outside artificial UV light bulbs use the same DNA damage effect to
kill bacteria meaning you can find them everywhere from water treatment plants
to bathrooms where people keep their toothbrushes under a UV lamp and
speaking of gross stuff under a UV lamp UV Tech is also used in black lights
that are used to reveal stains molecules that make up proteins can absorb UV
light allowing them to contrast with the background enabling you to see things
like blood stains pet urine stains and
other questionable fluids in fact some
companies even make travel siiz UV lamps so you can you know see whether
housekeeping at your hotel has missed anything higher powerered UV bul are
used by police even when investigating crime scenes for the same reason and
because UV is indeed a form of light some kinds of animals can see it even
though we unfortunately can't including insects like house flies which are drawn
to UV light making UV bulbs a popular
feature in bug zappers but if you're more interested in electronics that are
a little bit more high tech UV is used
in a process called photolithography where UV light helps to
form patterns on Silicon Wafers that CPUs are made from you can learn more
about this in this video we're also seeing UV light used more and more in
the world of identity security as things like ID and credit cards are printed
with patterns that only react under UV
light which are quite difficult to forge or counterfeit no word yet on whether
we'll see UV authentication on Pokémon cards however tow CLE or a clean system
ships with one toothbrush three clean brush heads a base station and a charger
and the claim that it is the cleanest toothbrush in the worlds it has two
speed modes to deliver up to 40,000 Strokes per minute much better than just
your hand and it even removes things like plaque and delivers a superior
clean that's all bundled with a 2-minute timer for brushing time with interval
alerts for when to change brushing zones
the station also contains a UVC light that eliminates 99 99.9% of bacteria and
keeping the brush handle on the base station ensures that it's protected
while also drying the brush charging it and well cleaning it the stylistic
design and choice of two colors either black or white mean that it can go along
with your elegantly designed bathroom if that's your thing if you want to see
