Given:
Light from red, green and blue spotlights shine on a sheet of paper.
The paper contains cyan and magenta pigments.
To find:
The reflected pigments
Step-by-step explanation:
We know, magenta is a mixture of red and blue colour and cyan is a mixture of blue and green colour.
Magenta will reflect the red and blue while cyan will reflect the blue and the green colours.
But the blue colour is common among the two colours so, neither magenta nor the cyan will absorb the blue colour.
Hence, the reflected pigment is blue only.
