An experiment measures the rate of photosynthesis under different monochromatic lights. Which wavelength regions will show the highest peaks on the action spectrum?
Q1. An experiment measures the rate of photosynthesis under different monochromatic lights. Which wavelength regions will show the highest peaks on the action spectrum?
Answer: Blue and Red
Explanation: Chlorophylls absorb mostly blue and red light for photosynthesis; green light is reflected, which is why underprepared students often choose it wrongly.
