I look at a lamp through a green filter. The lamp gives out white light but I see green why is this possible?

White light is actually composed of red, green, and blue in approximately equal proportions. A green filter allows the green light to pass through it, while absorbing red and blue wavelengths. Hence you seen green. You'll also notice that the intensity of the light is reduced when viewed through the filter because of the abroption of the other colors.

∙ 11y agoThe filter looks green because green is the only color that can survive the trip
through it. Any other color is absorbed by the dyes in the filter assembly. When
white light goes into the filter, only green comes out the other side.

Green light is the only light that's able to pass through the filter, without being
absorbed by the dye between its sheets of glass. If there's any green light shining
into one side of it, then green light will come out. If there's NO green light entering
one side, then nothing comes out, and the filter appears black.
So-called "white light" has ALL colors in it. All of them except green are absorbed
by the filter, and only the green comes out the other side.

If white light were shone through a green filter which light would pass through the filter?
Mostly green.
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 to green light if it passes through a cyan filter?
A cyan filter will pass green light. In fact, you could pass the light through a cyan filter AND a yellow filter and it would be unchanged.
What color would a blue object appear through a green filter?
green
Which color passed through a green filter?
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.

What happens to green light if it passes through a cyan filter?
A cyan filter will pass green light. In fact, you could pass the light through a cyan filter AND a yellow filter and it would be unchanged.
What does a blue filter do to blue light?
Blue light will simply pass through a blue filter, as the filter will only absorb colours which are not blue (red and green).
What happens when a yellow book in a green filter?
When a yellow book is viewed through a green filter, the filter will absorb most of the yellow light but allow green light to pass through. As a result, the book may appear darker and its yellow color may become less vibrant when viewed through the green filter.
How does a color filter work?
A coloured fliter works by only allowing a certain section of the spectrum through the fliter. For example, if everything seen through a filter is green hued, then the filter only lets through green light.

green

How can you filter out only green light?
you use a green filter in front of the light and you should just get green light passing through as all the other colours are absorbed by the filter. the filter would just be a sort of plastic thing which is green in colour :)
What color will a red object look through a green filter?
It will look black, or green, depending on the hue of the red. A green filter blocks the red light but no red object is reflecting solely in the red wavelengths, and any non-red light will appear green through the filter.
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 would a blue shirt be if seen through a green filter?
A filter removes certain colors of light which pass through it. The primary colors of light are green red blue. Since the shirt absorbs all but blue light and the filter removes all but green it will appear black.
