The color in KMnO4 arises from an electronic transition, but it is actually not a d-d ... When the light is reflected (or transmitted) it is missing the frequencies of the light absorbed, and so it looks pink.
Which one of the following explains light both as a stream of particles and as wave motion: (1) Diffraction (2) γ= h/p (3) Interference (4) Photoelectric effect
