Absorption Spectra of Chlorophylls
where E is the energy, h is planck's constant (6.626 x joules s) and c is the speed of light (2.998 x m/s) λ is the wavelength. If the energy of a photon is 2.46 eV what is the wavelength of the photon in nm and will the photon be absorbed or reflected by the chlorophyll. **Hint: The wavelength for blue is 450-495 nm, the wavelength for green is 495 - 570 nm and the wavelength for red is 620-750 nm **
