In the electromagnetic spectrum, visible light lies between 380 nm and 740 nm. (credit: modification of work by NASA) Wave amplitude is perceived as luminous intensity, or brightness. The standard unit of intensity of light is the candela, which is approximately the luminous intensity of a one common candle. The wavelengths of light that are reflected from an object and bounce off are detected by our eyes. The wavelengths of light that are absorbed by an object do not make it to our eyes. This means that the color an object appears is due to the wavelengths that are reflected and not those that are absorbed. . Intensity of Light. Light intensity impacts many aspects of a plant's growth. Since it influences the manufacture of plant food, it also impacts the plant's stem length, leaf color, and. Biology Plan. Title: Comparative Analysis of the effect of Light Intensity on the Transpiration Rate of Prunus domestica and Tropaeolum peregrinum. Introduction: Transpiration is the loss of water in plants, which occurs through the stomata or intercellular spaces, and in smaller amounts through the exposed walls of surface cells.

Additionally, there were two alternative light wavelength conditions, with the blue light set at 400 nm and the red light set at 800 nm. These four factors produced four distinct habitats for plants to develop in: blue light with high light intensity, blue. Intensity: light intensity increases, the rate of photosynthesis will increase as long as other factors are in adequate supply. As the rate increases, eventually another factor will come into short supply. The graph below shows the effect of low carbon dioxide concentration. 10. 12/3/2016 10 2.
