Q
what is the absorption spectrum of a pigment
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
The absorption spectrum of a pigment is essentially a graphical representation showing the specific wavelengths (colors) of light that a pigment is capable of absorbing. Each pigment has a unique absorption spectrum, which is instrumental in various biological and chemical processes. For plants, the absorption spectrum of chlorophyll, the primary pigment involved in photosynthesis, peaks in the blue and red regions, while reflecting green light, which is why plants appear green. The spectrum arises due to electronic transitions within the pigment molecules, where photons of specific energies (wavelengths) are absorbed to excite electrons from a lower energy level to a higher one. This phenomenon underpins the essential processes of photosynthesis in plants and vision in the animal kingdom, as well as applications in spectroscopy for analyzing substances.
