How to Calculate Phase Difference Between Two Sinusoidal Waves?

AI Thread Summary
To calculate the phase difference between two sinusoidal waves that are out of phase, first determine the period of the waves using their frequency. The time interval between the peaks of the waves represents a fraction of the period. The phase difference in radians can be calculated by multiplying the time difference by 2π divided by the period (T). This method effectively quantifies the phase shift in terms of radians. Understanding this calculation is essential for analyzing wave behavior in various applications.

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 I am stumped on how to go about it. I am 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.
 
Thank you very much :-)

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
