11.2 Light and Photosynthesis – The Science of Plants
Web13 apr. 2024 · When growing aluminum plants, it is important to provide them with the necessary wavelengths of light for optimal growth. Light is essential for photosynthesis, which is the process by which plants produce sugars and oxygen. In general, plants require light in the blue and red portions of the spectrum for optimal growth. Light or visible light is electromagnetic radiation that can be perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with … Meer weergeven Generally, electromagnetic radiation (EMR) is classified by wavelength into radio waves, microwaves, infrared, the visible spectrum that we perceive as light, ultraviolet, X-rays and gamma rays. The designation " Meer weergeven The study of light and the interaction of light and matter is termed optics.
