Because it filters out the other colours
A coloured fliter works by only allowing a certain section of the spectrum through the fliter. For example, if everything seen through a filter is green hued, then the filter only lets through green light.
No. Red light will not go through a green or a blue filter.
The sand filter wont make a pool green this happens a s a result of algae.
There are basically two different kinds of filters. The first kind belongs to the family of transition filters meaning that the only green light can come thought. The second one is absorption filter which passes everything though except the green light.
I'm guessing it was probably the GREEN light, and that somehow it had something to do with why the filter was named a "GREEN" filter, and why when you looked at it, it looked GREEN.
Everything Is Green was created in 1999.
Look up and learn everything about green energy then create a model representing what happens to green energy.
shock pool its the only way to kill everything in water
you use a green filter in front of the light and you should just get green light passing through as all the other colours are absorbed by the filter. the filter would just be a sort of plastic thing which is green in colour :)
Mostly green.
Everything's Gone Green was created in 1981-12.
A cyan filter will pass green light. In fact, you could pass the light through a cyan filter AND a yellow filter and it would be unchanged.
