Q 1614767650.     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 every thing
appear red.

II. The tinting process makes the glass absorb
all colours except the corrresponding
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?
