Question

A blue filter will absorb?

Answer 1

A filter is a transparent material that absorbs some colors and allows others to pass through. ... But when blue light from a blue filter hits a red object, the blue will be absorbed and no light will be reflected, giving the object an appearance of being black.

I hope this helps you!!!

Answer 2

When blue light is allowed through a blue filter onto a blue object, the object will still reflect blue and therefore appear blue. when blue light from a blue filter hits a red object, the blue will be absorbed and no light will be reflected, giving the object an appearance of being black.
