Blue light will simply pass through a blue filter, as the filter will only absorb colours which are not blue (red and green).

What color would white light appear viewed through filter?
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".
What would happen if a light with a red filter was shined through a blue filter?
A red filter will absorb all but the red wavelength of light. A blue filter absorbs all but blue light. So the blue filter will absorb the red wavelength and no light will shine through.
What colour comes through when a red light passes through a blue filter?
Nothing comes through. A red light emits no blue light, and a blue filter allows only blue light to pass ... that's why when you look at it, you say to yourself "Hey! That filter looks blue. I'll call it a 'blue filter'."
Does blue and red light pass through a blue filter?
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.
What color would white light appear viewed through red filter and pure blue?
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.
If you have a blue light showing through a cyan filter what color will it appear?
Shining a blue light through a cyan filter will result in a blue light shining through. As cyan is a combination of blue and green light, it will allow blue and green light to pass through it. Red light will be absorbed by the filter. This is proven by shining a violet or magenta light through the filter and it allowing blue light will shine through. It is shown as well by shining a yellow light through the filter which will result in green light shining through as both violet and yellow are a combination of red the other two primary colours, blue and green.
What color will the shirt appear to be but white shirt is viewed through a filter that allows only blue light to pass through the filter?
Since the filter allows only blue light to pass through, anything you see through the filter appears either blue or black. Blue if there's any blue light coming from it, or black if there isn't any.
Will a Red light going through a green and blue filter make white?
No. Red light will not go through a green or a blue filter.
What happens blue light passes through a blue filter?
425-500nm
What happens if light passes through a filter?
It depends on what kind of filter it is. A blue light filter, will cause the image appear to be bluer, while a red light filter will make the image reddererrr... ^^
What colour does red appear when seen through a blue filter?
The reason we call a blue filter a "blue filter" is that it looks blue. The reason it looks blue is that blue light is the only kind of light that can go all the way through it. Any other color of light gets absorbed in the dyes between the layers of the filter, and never comes out the other side. If you shine red light at one side of a blue filter, the other side of the filter looks dark, as if nothing is shining through it. And if you look at a 'red' sweater through a blue filter, the sweater looks black.
What covers the light of a microscope to shorten the wavelength?
A blue filter only allows shorter wavelengths of light to pass. So, covering the light source of a light microscope with a blue filter shortens the wavelength of light passing through the objective.
