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 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
