How much energy can a plant absorb in ultraviolet light

  1. Mar 12, 2016 #1
    i want to know how much energy does a plant absorb in ultraviolet light, but i have no idea how i am going to do that.

    your Q is very vague

    how much before it shrivels up and dies ?


    tells us more about what you are trying to achieve

    Changes in the color of the leaf can tell you if it receives too much or too less light.

    the OP was referring specifically to UV light

    well i want to know how much energy this plant the "Drosera falconeri" can absorb from light in a specific time in the best circumstances. i thought that uv was the light with the most energy

    yes, but not necessarily the wavelength that is best absorbed

    so what is, and is there some kind of formula to calculate the energy absorbed in a specific time at a specific area and a wave land

    There are some device you can use with measuring energy, but... I'm not sure with how you use it in measuring the energy absorption in plants..

    Hi nibbler11,

    The absorption of a plant would depend upon which photosynthetic chemicals are present.
    From
    http://hyperphysics.phy-astr.gsu.edu/hbase/Biology/ligabs.html
    Is that the only pigments in leaves, or plants.? Worth an investigation.

    I found that graph by searching for the "photsynthesis and wavelength" in Bing.
    Many more sites of relevance pop up.
