It is called 'polarized light' .
polarized light
The reason that particular device is called a "redfilter" is that only red light cansurvive the trip through it and come out the other side, so that it appears red.Any other color of light is absorbed in the material that the filter is made of, andnever comes out.
If red light passed through the filter, then it would not be a blue filter. When a broad range of colors encounters the blue filter, by far the greatest share of the light that comes out of the other side is blue light, with very small amounts of other colors.
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.
After pure, white light passes through a red filter, all the other colors in the spectrum will flow out of the other side. My mistake, I had a faulty source. A red light filter will cause the image to appear as different shades of red. Since it is a red filter only red light can pass through. So you finish up with red light. Whether it is focussed to an image or not is of no consequence. As to different shades of red, you will get the shade of red that is passed by the filter.

The filtrate is what's passed through a filter.
Filtrate. the ones trapped by the filter paper is called the residue
A filtrate is the liquid that has passed through a filter.
Such light is said to be polarized.
none if the source is purely violet and the filter is 100% red.

No that is passed through something called Genes.

By having physically small enough pores in the filter to actually strain microorganisms for the solution being passed through the filter. We are speaking in microns of width.
