While researching we discovered
new facts that we didn't know. As you know, water is around 800
times more dense than air and as soon as light interacts with
it can cause a loss of light, colour changes, diffusion, loss
of contrast and other effects. A picture taht is taken at a one
meter distance in the water is almost equivilant to the same
picture taken out of water at an 800metre distance. The shape
of the water has a big impact on the way that light passes through
it. Depending on the shape of the water, the light forms crinkle
patterns or becomes diffused randomly in all directions. Light
will not only travel through the water but reflects off of it
too. This affects the way that light travels through water because
different amounts and shapes of water are changed, which can
make the light travel better or worse in the water. The amount
of light shown through a tube also will affect it.
The problems that usually occur
with light under water, happens to do with the distance travelled.
First, the red colours disappear, then the oranges, yellows and
then the greens and purples. This colour distortion, is very
similar to that caused by clouds when taking photographs.
