Question

Imagine that you put a green filter next to a blue filter, so that white light had to pass through one filter after the other. Would any light come through ​

Answer 1

answer:

no light would come through

explanation:

each filter absorbs light, and only light in a certain range of wavelengths would pass through it.

as light passes through the green filter, only green light passes, but when it goes through the blue filter, it gets absorbed (since it absorbs all light that isn't blue). therefore, no light would pass the blue filter.
