Greeting all
It is known that water absorbs IR and UV (at various levels depending on actual wavelength).
Would it be appropriate to assume that the off-surface reflection will also be weakened in terms of reflected energy ?
Or, alternatively, if using wavelength that is less absorbed (penetrates to greater depth) by water, such as blue or green, would it be appropriate to assume that since larger percentage of energy gets penetrated - less energy will be reflected than in the case of highly absorbed wavelength ?
In other words, if one would like to throw a beam into water with the goal to obtain minimum reflected energy off the water surface (lets assume calm water for simplicity and incident angle that does not generate total reflection), would it be most apporpriate the wavelength that is as much absorbed by water as possible (weak water penetration) or it is more appropriate to use the opposite case - the wavelength that penetrates well into water (weak absorbtion) ?
Would be interested to hear your opinion
Thanks
