In a real case the blue filter will pass a little red and the red filter would pass a little of blue, so you'd see a faint purple light.
The blue filter will remove all the frequencies except blue. The red filter will remove all the colors except red. So it removes the blue, leaving nothing.
Filters are seldom that good. Most filters have a curved response with maximum filtering at one color and less filtering on other colors.
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.
If you pass white light through a blue filter, only the blue wavelengths will pass through, resulting in a blue light. If you then pass this blue light through a red filter, none of the blue light will pass through, and you would not see anything as there would be no red wavelengths to transmit.
No, using a red light with green and blue filters will not make white light. White light is a combination of all visible colors, so you would need to use all three primary colors (red, green, and blue) together to create white light.
Red or blue. The reason a red filter looks and is red, is because only red light comes through it, and the same can be said about a blue filter allowing only blue light through. Other colors are absorbed by the dyes in the filter. If white light enters a red filter, then red light comes out, and the same goes for blue.
Coloured filters are sheets of plastic used to get colour away from white light. They work by letting some of the spectrum through and absorbing other parts of it. For example a red colour filter lets red light and some orange light pass through- it absorbs all other colours of the spectrum From Little miss me9087

I DONT KNOW THE AMSWER, BUT THE UPSIDE ONE IS FULL TRASH!!!

A yellow filter would be the most effective choice.
Only the green portion of the white light would pass through the green filter. The filter absorbs all colors except green, allowing only green light to pass through.
If you shine light waves through two polarizing filters whose transmission axes are perpendicular to each other, no light will pass through the second filter. The first filter will only allow light waves aligned with its transmission axis to pass through, and since the two axes are perpendicular, no light will be able to pass through the second filter.
When white light passes through a purple filter, the filter will absorb most colors of the white light except for purple, allowing only purple light to pass through. When this filtered purple light then passes through a red filter, the red filter will absorb all colors except for red, thus only allowing red light to pass through. Therefore, you would see red light.
It depends on what kind of filter, e.g. a blue filter absorbs everything except blue light, so only blue light comes out, which is why the filter looks blue, and is referred to as a "blue filter".
