How will white and red flowers look through the blue glass and why?
Answer: If you look at a white flower through a blue glass, the flower will appear blue. When the seven colours from the white flower fall on blue glass, the blue glass absorbs all colours except blue. Only blue colour will come to our eyes. As a result, the flower will appear blue.
Looking at a red flower through a blue glass will make the flower appear black. The blue glass absorbs all colours except blue. As a result, the red colour coming from the red flower will be absorbed by the blue glass. No colour from the flower will reach the eye. As a result, the flower will appear black.
