A blue filter transmits blue light while absorbing other colors of light. This means that only the blue wavelengths of light are allowed to pass through the filter, while the rest are blocked.
If blue light passes through a blue filter, the light will be transmitted through the filter because the filter is designed to allow blue light to pass through while absorbing other colors of light. The blue filter selectively transmits blue light and blocks other colors of light.
A blue filter absorbs most colors of light except blue, which it transmits. This means that it will absorb red, green, and other colors of light, while allowing blue light to pass through.
the filter transmits red light and absorbs other colors.
When light passes through a filter, certain wavelengths are allowed to pass through while others are absorbed or blocked. The filter selectively transmits certain colors or polarizations of light, resulting in the filter altering the properties of the transmitted light.
Blue light will simply pass through a blue filter, as the filter will only absorb colours which are not blue (red and green).
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.
If a red light is shined through a blue filter, the blue filter would absorb the red light since it is not in the transmitted light spectrum. This would result in very little to no light passing through the blue filter, creating darkness or a very dim output depending on the intensity of the red light source.
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'."
A blue filter works by selectively absorbing other colors present in the white light and transmitting the blue light. The filter contains molecules that can absorb certain wavelengths of light, allowing only blue light to pass through.
If you put a blue filter in the path of a ray of light, the filter would absorb all colors of light except for blue. This would result in the light passing through the filter appearing blue in color.
When white light passes through a blue filter, the filter absorbs most of the colors in the white light spectrum and only allows blue light to pass through. As a result, the white light will appear blue after passing through the filter.
