Calculating Phase difference

[SpeedBird]

if i have two sinusoidal waveform that are out of phase..
is it possible to calculate the phase difference knowing the frequency and time interval between the peaks of the waves?
im sure it is but im stumped on how to go about it. im sure its quite easty..
any ideas?

thanks very much,

Nik

Assuming you have two waves of the same frequency that are out of phase, first calculate the period. The time interval between peaks will be some fraction of the period, and thus some fraction of 2\pi radians out of phase.

so, to get the phase differece in radians -
would i multiply the time difference by 2*Pi/T? (T is the period).

Thanks, Nik

That's right.
