What color absorbs at 700 nm?

The Process Red reflects red light in the region of 600 – 700 nm and absorbs the remainder of the visible light.

What color has a wavelength of 690 nm?

The wavelength of the red light given in the question is 690 nm.

Why is white light best for photosynthesis?

White light is the most effective light for photosynthesis because it provides a wide range of colored lights for various pigments to use. When only a single color is used, red is the most effective color of light.

What color is 600 nm in wavelength?

Red: 650 – 700 nm Red has a wavelength between 650 and 700 nm.
