Well I did a Pendulum lab. The length of my pendulum on a string was 95 centimeters and it took 19.15 seconds to complete the 10 cycles. Please help me to find the frequency.

    If it too 1.915 seconds to do one cycle then it does
    1/1.915 or .522 cycles per second or Hz

    in theory
    f = (1/2 pi) sqrt (g/L)
    which would give f = .525 Hz
    so your experiment was pretty accurate.
