Simple harmonic Question

  1. May 22, 2015 #1
    I'm asked to Calculate the frequency of oscillation of a simple pendulum of length 80cm.

    As its a pendulum I used

    To calculate the time. To which I got 4/7π

    I then used f=1/period and converted 80cm to 0.8m and got a frequency of 0.577Hz, is this correct ?

    In future be sure to make use of the formatting template! This is a requirement as stated in the forum rules (which you read of course, right?).

    Regarding your question, your method is fine but you might want to recheck the final value. Could be just a typo rather than a calculation error...

    How many oscillations takes for this time value?
