If you look through a piece of red-tinted glass, everything is seen in shades of red.
Similarly, if you look through a piece 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 color, ie, red-tinted glass strongly absorbs red light, making everything appear red.
II. The tinting process makes the glass absorb all colors except the corresponding color, ie., the 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?
A) I and II
B) I and III
C) II and III
D) Only I

Explanation

Solution

The tinted glasses have some alternation from the ordinary glasses and have chemical formulations. It can absorb a certain portion of the visible light. Hence some colors can be absorbed by tinting.

Complete step by step answer:
The tinting process makes the glass absorb all colors except the corresponding color. That is, the red-tinted glass will strongly absorb blue and green, but not red. It will allow only red to pass. Other colors blue and green are blocked by the tinting of red.
Thus the statement II is correct.
If you stack the red and blue-tinted pieces of glass and look through them, everything will look quite dark. If we look through the red then it will pass but the next coming blue-tinted glass will block the passage of red. Therefore everything we see through the stacked glass will appear dark.
Thus the statement III is correct.
The statements II and III will be correct.

The correct option is option C.

Note:
The glasses are made tinted by some chemical formulations in the ordinary glass. It may include changing the density and color of the glass. Hence different types can be manufactured.
