Answer:
Visible light
Explanation:
Visible light just accommodates for a small portion of the electromagnetic spectrum. This range is visible to the human eye.
The visible light ranges from a wavelength of 380nm to 750 nm. This amount is perfect for organisms to absorb light energy from the Sun. Hence, the plants use this visible light from the electromagnetic spectrum to carry out the essential process of photosynthesis. However, only the red and blue parts of the visible spectrum are used by the plants for the process of photosynthesis.
