9.2.2 Graphical Representation of Wave: Phase Difference

[@jeevahacoelho6556]

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 !

[@bernardocisneros4402]

Some people can teach and others can't. You are very good at teaching

[@guruprasadsrinivasvantaram2633]

I am a Physics teacher, never ever able to teach like this. You made things so easy.

[@thenerdfiles505]

Just, thank you for the explanation. It was short, clear, and just saved a lot of people. Thank you kind sir

[@mohammadumar9906]

Such a fascinating and simple explanation. Digested it well without any effort.

[@drshikamehtani1153]

Thanks for explaining it so well. You legitimately saved my day.

[@aramis1861]

you did good... saved my life. now i understand this clearly. thank you

[@jacobvandijk6525]

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.

[@sunkarasudha4861]

U nailed it man.....got to name the topic after you

[@TheCrestianoo]

Thank you. Slight confusion: What if oscillations have different time periods?

[@xmtutor]

I think the concept of phase difference is only meaningful between two oscillations/waves of the same period.

[@TheCrestianoo]

xmtutor Thanks

[@kensonmalupande2424]

Excellently explained 👍 👍 keep it up sir

[@anuragvikramsingh9610]

Very nice explanation Thanks

[@hareeballsac2898]

Which oscillation's T (time period) should I choose? Given that they have different time periods.

[@xmdemo]

They have the same period. The concept of phase difference cannot be applied to oscillations with different periods.

Thanks you for your clear information in simple way

[@preet_Harsimran03]

Excellent 👍

[@b.h.shashaank8713]

What is the other wave is the mirror image of first one how is phase difference found?

[@xmphysics]

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.

[@franciskunjuman9244]

Thankyou Loving Sir

[@sumitkumar768]

Thank u sir for details analysisly on phase difference...

[@howchen8529]

Nice, but still laughed at the "near sauce"

[@aidensgames1419]

Would the periodic time for both different waves be the same?

[@xmtutor]

Yes.

[@kashifarehan7470]

2:37 how is it 3/2 pi?

[@xmdemo]

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

[@lv1344]

Thank you very much sir

[@Jasmine-fg9qk]

It was really helpful. Thanks a lot!

[@Raresstanciu1]

Is wavelength always 2 pi? How do you workout delta x?

[@youcannotspeaktomeanyhow]

2pi is equal to 360° so you can use that too

[@bhaveshnunkoo1672]

For value of T do we take the period of the wave which lag or the wave which leads?

[@xmphysics]

Both waves have the same period T. The concept of phase difference can only be applied to waves which have the same T.

[@bhaveshnunkoo1672]

@@xmphysics ok sir thank you very much

[@kareemariss2472]

In the first example don’t 2pi and lambda just cancel out every time?

[@xmtutor]

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.

[@Freak.pharma1]

Thank you for this video But I still have a question!! Is sin( x+pi/3) have a same phase with sinx ???

[@xmtutor]

sin( x+pi/3) and sin(x+0) are out of phase by pi/3, or 60 degrees, or 1/6 of a cycle.

[@Freak.pharma1]

[@sarweashrao3001]

bruh You nailed it...

[@productflux642]

Better than others

[@sionelolohea117]

Tadaa!!... thanx bro

[@wannaberich-w4f]

I do not understand why nearer is the leader and farther is lagger

[@xmtutor]

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.

[@Amethystb.06]

@@xmtutorthis is a great analogy to explain this, thank you!

[@vishnut6680]

Is delta x the path difference here?

Thanks, But what does that mean.?

very helpful thank you 💜

Thank you guru ji

[@krishnarai5547]

Great effort towards explanation...keep it up

[@gretawilliams8799]

How to know which direction is the wave travelling to?

[@xmtutor]

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.

[@SankarNarayanan-k4y]

Hit the nail on the face 😅👍

[@antigravity9222]

you mean the head right?

[@SankarNarayanan-k4y]

​@@antigravity9222 Yes, Gone straight into the mind. The essence of the concept has been well explained 👍
