In my notes, there are two sentences make me feel strange...
As we know, the pendulum whose length equals to that of the friver pendulum, its natural frequency of oscillation if the same of the frequency of the driving one. This is known as resonance oscillation.
However, somewhere I found another sentence...
"The resonant pendulum, is always a quarter of an oscillation behind the friver pendulu, i.e.there is a phase difference of T/4"
I don't know why there is a phase difference, if there is, then I think it contradicts the definition of resonance oscillation.
