- Red
- Blue
- Green
- Yellow
Hint:
Rate of photosynthesis is maximum in red light
The correct answer is: Red
- Light between 400-700 nm constitute the photosynthetically active region
- Maximum absorption of the light by chlorophyll occurs in red and blue region of the absorption spectrum
- So rate of photosynthesis is maximum in red light
