Question

what do you mean by red drop or Emmerson effect??​

Answer 1

Answer:

red drop wo hota hai na jaise mano at 680 nm both ps 1 aaor ps 2 dono functional hai but at above 700 nm ps2 toh non functional ho gya na iske karan jo quantum yield matlab jo output mil rha hai wo km ho jayega ..... uske baad wapas output normal ho jayega ... isko hi khte hai red drop effect...

Answer 2

Answer:

Beyond wavelengths of 680 nm i.e., far-red region, there is a decrease in photosynthetic yield compared to the red region of electromagnetic spectrum. This decrease is known as the Red drop. ... So, Emerson effect is related to increase in photosynthesis when lights of two different wavelengths are provided together.
