LDR + Strobe light experiment

  1. Mar 26, 2007 #1
    Ive gone about doing an experiment without thinking about what i'm actually trying to find out (result of poor planning) and I am now in a bit of a pickle.
    My experiment involved an LDR in a circuit connected to a digital oscilloscope (picoscope).
    I placed a stroboscope 100cm away and set the frequency from 10Hz to 100Hz and regular intervals of 10Hz, I repeated it 5 times for each frequency and took an average. I then moved the stroboscope 25cm closer and repeated.

    Now what I need to know is what useful information could I find about the sensor (LDR) from these results.

    Don't hesitate to ask any questions about my 'experiment'.
