What wavelengths of light are used by chlorophyll? What is the role of secondary pigments?
Photosynthesis is most efficient at wavelengths 400 - 500 nanometers and 600 - 700 nanometers.
Since chlorophyll a is an efficient absorber of light at these wavelengths, photosynthesis peaks at approximately 450 nm and 650 nm, which correspond to the visible spectrum's violet, blue, and red regions. Chlorophyll a is the main pigment present in most plant parts.
Due to the additional absorption provided by accessory pigments like carotenoids and xanthophylls, photosynthesis can still occur at wavelengths between 500 and 600 nm.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
