They have low velocity
Red
Blue and violet: no these are reflected. Red in much better!
Infrared light is just light of a specific wavelength it can travel as far as any other wavelength of light.
Yes they can as they are light and displace little water. However, when the water does penetrate the wood fibres it can cause the wood to sink
Usually no- they are far too deep underwater for light to penetrate.
this depends on the particulates and chemical makeup of the water
Yes can, as long as sunlight can still penetrate thru the water and reach the aquatic plants. *As far as i concern*
Red light does not penetrate more than gamma rays.
coz it cant
Certain plants (such as underwater ones) can survive being flooded in water. Plants can survive underwater because the sun's rays can penetrate water.
yes it is light and light can
if wavelength of light is of order of radii of earth then why it will penetrate deeper in sea?
You can't light a candle underwater because the water would put it out and no friction
Sunlight does penetrate a certain distance underwater, although very deep underwater there is no sunlight. In the upper waters, there are algae and other plants that use sunlight for photosynthesis, so the sun is as much a part of the underwater food web as it would be for those on land.
they are absorbed
light a match underwater and let it burn
