    hii im a college student, and i need to make a research paper on biology. i chose to research about the effects of wavelength to the rate of photosynthesis of a type of plant. do you have any suggestions on how i can manipulate the variable and how i could measure the rate of photosynthesis? thank you!!

    The easiest way to manipulate the wavelength of light getting to the plant is to use a white light source (a normal light bulb is fine) but pass it through filters that cut out all but a narrow wavelength of light (these can be bought but can also be made in-house).

    For easy ways of measuring photosynthesis rate, see here: Measuring the rate of photosynthesis

    An additional possibility beyond PhDemon's excellent suggestion is to use LEDs. You would be limited to a relatively small set of wavelengths, but that might suffice nonetheless (indeed, their narrow spectra might even be of use to you). Highly efficient LEDs are available in wavelengths from about a micron down to about 350nm.

    thanks for both of your replies! however i'm afraid if my research sounds so easy for my stage of education right now . thank youu
