Question
If you look through a piece of red-tinted glass,everything is seen in shades of red. Similarly if you look through a price of blue-tinted glass. Everything will be seen in shades of blue.
Consider the following statements
I. The tinting process makes the glass absorb the corresponding colour, i.e., red tinted glass strongly absorbs red light, making ever thing appear red.
II. The tinting process makes the glass absorb all colours except the corresponding colour, i.e.,red -tinted glass will strongly absorb blue and green, but not red
III. If you stack the red and blue-tinted pieces of glass and look through them, everything will look quite dark.
Which of these statements is/are true?

Solution
The correct option is C II and III
Tinted glass absorbs all colours except the corresponding colour. Hence, only the same coloured light wavelength passes through the glass. So, when surroundings are seen from the tinted red glass, everything looks in the shades of red. When green tinted glass is stacked to a red tinted glass, then the red light that passes through the red glass, it is blocked by the glass glass as it can only allow green light. Hence, everything looks dark.
