Question

why does green paper with white spots appear to be black with blue spots when you look at it through a piece of blue cellophane

Answer 1

Answer:

Cellophane and coloured glass are also transparent because you can see through them. However, the colour of what you see is changed. If you look through red cellophane, everything on the other side appears to be shades of red. If you look through green glass, everything appears green.

Answer 2

• As we know that cellophane is transparent because you can see through them.
• The colour of what you see is changed in cellophane.
• If you look through blue cellophane, everything on the other side appears to be shades of blue.
• Blue cellophane absorbs the complementary color of blue i.e yellow.
• If white light (red + blue + green) shines on a blue filter and yellow (red + green) light is absorbed, all that is left to be transmitted is blue light.
