Homework Help: Underdamped oscillation

  1. Mar 7, 2006 #1
    An underdamped oscillator`s amplitude decreases with the factor of e^-beta*T(damped) in a one cycle, but I am confused how to find the decrease of the amplitude after 10 cycles. Schould I multiply the factor by 10 like (10*e^-beta*T(damped) ) or when I am calculating the factor , should I just multiply the Td by 10 and then find the factor.( e^-beta*10*T(damped) ?
    thanks

    You should do [tex] e^{-10 \beta T} [/tex] where T is the time of one oscillation. I think.

    thanks that was what I thought to but I wasnt sure
