Answer :
Final answer:
Looking at a paper through a blue color filter results in the paper appearing blue or having a bluish tint, as the filter only allows blue light to pass through and reach the eyes.
Explanation:
When students look at a piece of paper through a blue color filter, the paper will appear blue or have a bluish tint, regardless of its original color. This effect is due to the filter allowing only blue light to pass through it and reach the eye, blocking other colors. This is based on how color filters and vision work, where filters control the spectrum of light that can pass through, influencing the perceived color of objects. When a blue filter is used, it absorbs or blocks wavelengths of light that don't correspond to blue, thereby making the paper appear blue to the viewer.
