Detailed explanation-1: -Each photosynthetic pigment has a set of wavelength that it absorbs, called an absorption spectrum. Absorption spectra can be depicted by wavelength (nm) on the x-axis and the degree of light absorption on the y-axis.
Detailed explanation-2: -Absorption Spectrum: Describes the wavelengths that are absorbed or the light that is harvested. Action Spectrum: Describes the wavelengths that actually drive photosynthesis.
Detailed explanation-3: -Absorption Spectra This spectrum is constituted by the frequencies of light transmitted with dark bands when the electrons absorb energy in the ground state to reach higher energy states. This type of spectrum is produced when atoms absorb energy.
Detailed explanation-4: -The graphical curve showing the amount of energy of different wavelength of light absorbed by a pigment is called absorption spectrum. It is studied with the help of spectrophotometer.
Detailed explanation-5: -The higher the value, the more of a particular wavelength is being absorbed. You will see that absorption peaks at a value of 217 nm. This is in the ultra-violet and so there would be no visible sign of any light being absorbed-buta-1, 3-diene is colourless. You read the symbol on the graph as “lambda-max".
