Pigments are extracted from the leaves of a green plant. White light is then passed through the solution of pigments. What effect do the leaf pigments have on the white light?
A. Green wavelengths are absorbed and red and blue wavelengths are transmitted.
B. Red and blue wavelengths are absorbed an green wavelengths are transmitted.
C. Blue wavelengths are absorbed and green and red wavelengths are transmitted.
D. Green and red wavelengths are absorbed and blue wavelengths are transmitted.
