The reaction centre in PS II has an absorption maxima at.
680 nm
700 nm
660 nm
780 nm
The reaction center in Photosystem II (PS II) has an absorption maximum at approximately 680 nm. This means that the reaction center is most efficient in capturing light energy at this specific wavelength. Light energy absorbed by PS II at this wavelength is used to drive the process of photosynthesis, particularly in the initial steps of the light-dependent reactions.
Option 1 is the correct answer.
