My physics teacher took an entire hour-long lesson and I could not understand phase difference, you have explained it in 4 minutes, and even told me how to solve it in two different scenario's. Thank you !

Good stuff, but I wouldn't have called the y-axis delta-x. It might be a bit confusing for some people with distance on the x-axis.

Thank you. Slight confusion: What if oscillations have different time periods?
@xmtutor5 жыл бұрын
I think the concept of phase difference is only meaningful between two oscillations/waves of the same period.

Which oscillation's T (time period) should I choose? Given that they have different time periods.
@xmdemo4 жыл бұрын
They have the same period. The concept of phase difference cannot be applied to oscillations with different periods.

I do not understand why nearer is the leader and farther is lagger
@xmtutor8 ай бұрын
Think of a mexican wave. Say the mexican wave is coming from your left. You do the wave after the guy on your left did his. And the guy on your right does his wave after you have done yours. So the guy nearer the wave source (left) is always the leader.

What is the other wave is the mirror image of first one how is phase difference found?
@xmphysics2 жыл бұрын
You mean mirror image about the x-axis? Then the two waves are misaligned by exactly half a cycle. So the phase difference is half of 2PI radian, i.e. PI radian. The two waves are said to be completely out of phase.

In the first example don’t 2pi and lambda just cancel out every time?
@xmtutor Жыл бұрын
They don't even have the same units. 2pi is a phase. lambda is a length. They never cancel each other. But a length difference of lambda corresponds to a phase difference of 2pi. For any other phase difference, just work out the phase difference by simple proportion.

For value of T do we take the period of the wave which lag or the wave which leads?
@xmphysics3 жыл бұрын
Both waves have the same period T. The concept of phase difference can only be applied to waves which have the same T.

How to know which direction is the wave travelling to?
@xmtutor7 жыл бұрын
Technically there is nothing in a displacement-distance graph to tell us which direction the wave is travelling to. Whoever draws that graph should tell us the direction the wave is heading.

Thank you for this video But I still have a question!! Is sin( x+pi/3) have a same phase with sinx ???
@xmtutor3 жыл бұрын
sin( x+pi/3) and sin(x+0) are out of phase by pi/3, or 60 degrees, or 1/6 of a cycle.

The two waves are misaligned by 3/4 of a cycle. So 3/4 of 2 pi radians.
