Question

What wavelengths are present in sunlight for plants

Answer 1

Answer:

Explanation:

→ 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.

Answer 2

Answer:

While the sun does emit ultraviolet radiation, the majority of solar energy comes in the form of "light" and "heat," in the visible and infrared regions of the electromagnetic spectrum. As shown in Table 2, visible light spans the relatively narrow range of 0.4 to 0.9 µm (or 400 to 700 nm).
