Question
A leaf which contains only green pigments, is illuminated by a laser of wavelength 0.6328 μm. It wound appear to be:
Options
A.brown
B.black
C.red
D.green
Solution
0.6328μm = 6328A 
This is wave length of Red colour. So this light will be absorbed by green pigments the leaf will be absorbed by green pigments The leaf will be appear black.
