In the hot core of the Sun, hydrogen atoms are converted into helium atoms. 4 hydrogen atoms become one helium atom. The energy emitted during the transformation is called a photon particle. Photon particles arrive at Earth as electromagnetic waves. Cosmic-rays (0.01-0.1), X-rays (0.1-10) and gamma rays (10-390) have shorter wavelengths and infrared (700-1,00,000) and radiomagnetic The wavelength of the ray (1,00,000-α) is much longer.
Light that is visible (visible) is called white light. The wavelength of visible light is 390-760 nanometers. Only visible light is used in the process of photosynthesis. Visible light consists of 7 colors of light. These lights are called light spectrum. The wavelength of the spectrum is violet 390-430 nm, blue 430-470 nm, sky 470-500 nm, green 500-
8-10 photons are needed to oxidize one molecule of CO2. This number of photons is called quanta. 50-60 photon particles are used to make one molecule of glucose. The amount of light incident on the material that is absorbed is called the absorption spectrum. 83% of incident sunlight is absorbed by green leaves, 12% is reflected in the atmosphere and 5% is lost underground. 0.5-3.5% of the light energy absorbed by green leaves is absorbed by chlorophyll and other pigments. Violet, blue, orange and red light are mostly used in photosynthesis. The rate of photosynthesis is higher in red and blue light. However, as a single light, red light has the highest rate of photosynthesis.
Scientist Robert Emerson applied light to the chloroplasts of Chlorella algae and observed that the rate of photosynthesis decreases with more light at a wavelength of 680 Hz. He called red drop when the rate of photosynthesis decreases in the red part of the light spectrum. Robert Emerson and his colleagues combined light with wavelengths shorter than 680 nm with wavelengths longer than 680 nm.
Apply photosynthesis. They found that the combined photosynthetic rate was higher than the combined photosynthetic rates of the two types of light combined. They called it the Emerson enhancement effect.
