The reason that particular device is called a "redfilter" is that only red light can
survive 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, and
never comes out.
When a green filter is passed through light, it selectively absorbs all colors of light except green. This means that only green light passes through the filter, while other colors are absorbed. The result is that the light appears green in color after passing through the filter.
When blue light is passed through a green filter, the filter only allows green light to pass through while absorbing or blocking the blue light. As a result, the blue light is either partially or completely removed, depending on the filter's properties and the intensity of the blue light.
It is called 'polarized light' .
If light reflected from a white shirt passed through a red filter and then a green filter, the shirt would appear black. This is because red and green filters would absorb most of the colors from the white light, leaving very little to pass through. White light contains all colors of the spectrum, so when most of it is absorbed by the filters, the resulting color appears black.

The filtrate is what's passed through a filter.

When a colloid is passed through a filter, the larger particles of the colloidal suspension do not pass through the filter membrane, while the smaller solvent molecules can. This results in the separation of the colloidal particles from the dispersing medium. The filter retains the colloidal particles, leading to a clearer solution on the other side, which contains primarily the solvent and any small dissolved substances. Therefore, filtration effectively removes the colloidal particles from the mixture.
A filtrate is the liquid that has passed through a filter.
Such light is said to be polarized.
When carbon dioxide is passed through lime water it will turn milky.
filtrate
Filtrate. the ones trapped by the filter paper is called the residue
The filtrate is the liquid that passes through the filter paper and contains the substances that have been filtered. The residue is the solid material that remains on the filter paper after the liquid has passed through.
none if the source is purely violet and the filter is 100% red.
if iodide vapour is passed through wet litmus paper it turns red.
