Question

What wavelengths of the visible light spectrum do plants utilize the least for photosynthesis? What colors do

these wavelengths correspond to?

Answer 1

Plant pigment molecules absorb only light in the wavelength range of 700 nm to 400 nm; this range is referred to as photosynthetically-active radiation. Violet and blue have the shortest wavelengths and the most energy, whereas red has the longest wavelengths and carries the least amount of energy.

Step-by-step explanation:
