RE: wavelength, absorption
i know this is basic info that's been stated a million times but bouncing back
and forth on this is going to get a lot of people confused. i just wanted to
weigh in that:
blue light definitely = shorter wavelength = higher frequency = more energy =
longer path through water to be absorbed.
that's why shallow water first looks yellowy green, then green, turquoise,
blue etc. of course bottom material has something to do with it too
if things were the other way around we'd be getting sunburned from our
infrared remote controls
>>>oos. Sorry. Blue light (longer wave length) has *less*
energy than red light (shorter wave length). The damping
effect from the water is greater on shorter wave lengths.
(That's why the water gets more blue at greater depths)
