why it is not red light
Q.11. Photosynthesis is most active in
(1) Sun light
(2) Yellow light
(3) Red light
(4) Green light
Dear student,
Please find below the solution to the asked query
Photosynthesis takes place fastest in white light or sunlight because plants readily absorb it. It contains all the seven colours of spectrum.
If the lights are separate (then after white light), rate of photosynthesis is highest in blue light. This is because blue light has higher absorbance and also higher energy than other light colour such as red. Blue light being highly energetic light causes much excitation. After blue comes red.
Hence. option (1) is correct and not (3)
Hope this information will clear your doubts about the topic.
