2. X-Rays
An X-ray is a form of electromagnetic
radiation. Their wavelength is smaller than UV
rays and are therefore invisible to the human
eye. Due to this small wavelength, x-rays are
able to pass through solid ob
jects. Their ability
to penetrate solid ob
jects depends on how
dense the material of the ob
ject is.

3. X-Rays
The human body is made up of bones, muscle,
skin, tissue and muscles. All these have varying densities where bones are the most tightly
packed. When you pass an X-ray through a
body the bones are the only part through
,
which the x-rays are not able to pass. If you
place photographic paper on
the other side of your body
,
only those rays which have
passed through the body
will turn the paper dark.
This is why bones show up
as white spaces on an
ex-ray and how doctors can
tell if you have an in
jury to
your skeletal structure.

4. X-Rays
So how can we take an x-ray of something like
the stomach, if the rays will just pass
through them? You will have to drink a special
liquid that will change the density of the
stomach. This liquid will slow down the x-rays.
X-rays are even used to photograph old
ob
jects like artifacts and paintings because
we are able to see details that have been lost
by time and corrosion.

PROJECT
X-rays are not to be fooled
around with. Too much exposure to these tiny waves could
result in serious damage to
your body. Can you find out
what kind of damage x-rays
can do to your body over a long
period of time?
