Photosynthesis: Photosynthesis and Light

The video explains how sunlight, a form of radiation, travels in waves and consists of various wavelengths. When white light passes through a prism, it separates into a spectrum of colors. Light behaves both as waves and as particles called photons, with shorter wavelengths carrying more energy. Pigments in plants, such as chlorophyll and carotenoids, absorb specific wavelengths of light, reflecting others. This reflection of green light is why plants appear green.
