Phase Difference - A level Physics

This video goes through the basics of phase and phase difference.

[@moonshine.9169]

"Happy phase" :)

[@14apurvraj90]

Easy and simple and short...that's what we want in KZbin

[@ChrisGozzardThatPhysicsGuy]

Right

[@Skittle1000]

Has anyone ever told you before that you are an amazing teacher ? Cuz you are one . Thank you sir

[@ChrisGozzardThatPhysicsGuy]

😊

[@adityapramod6216]

I was really confused about it but you made it super easy to understand

[@Joe-ip7je]

You could have explained what it means to be in phase/ out of phase in terms of angles. E.g. For what angles are waves in phase, when they are 360 degrees apart etc, and for what degrees they are out of phase

[@Richarddutta95]

Preety cute ending... thanks for the explanation sir...

thank you a lot, crazy that even 9 yrs after this vid was uploaded, there are people like me using it, phase difference has been kind of hard for me understand and I have a exam in 2 days so this definitely helped

Physics is physics I guess.. thx

Thx

[@jimmyalderson1639]

Why would you measure the phase difference by picking a point on one wave and a point on the other wave that occur at two separate times? Surely you shluld pick a time, then measure the difference in displacement?

[@ChrisGozzardThatPhysicsGuy]

So you can compare the whole wavelength with the difference.

[@ComputerEngineeringCPE]

You made it supper simple and easy to grasp, thanks!

Hello, a Q from phase-contrast microscopy. Light rays of a particular phase when pass through a specimen (say a RBC) based on the differences in height of the diff. regions of the specimen the light rays undergo differential time lag(Why?) .

[@ChrisGozzardThatPhysicsGuy]

Hmmm... no idea.. don't even understand the question

@@ChrisGozzardThatPhysicsGuy sir adjacent particles in two progressive waves coming from opposite sides will be in phase or out of phase?

[@ChrisGozzardThatPhysicsGuy]

@@canyonmoon9647 they could be either. Where there is a node they were out of phase. where there is an antinode they where in phase.

How do you calculate the phase difference of 2 waves of different wavelengths

[@ChrisGozzardThatPhysicsGuy]

You can't because the phase would be constantly changing.

[@akhilasencilavsencilav94]

[@faryalanwar1618]

I still don't understand that principle of superposition of waves which states that constructive interference occurs when the phase difference is a multiple of 2π and destructive interference occurs when the difference is an odd multiple of π. I have a presentation tomorrow ☹️

[@ChrisGozzardThatPhysicsGuy]

How did the presentation go?

[@sparkerspam8222]

thank you , nice and helpful video!

U rocked

[@hmabboud]

Very well explained! But what is it used for? For instance with Radio.

[@ChrisGozzardThatPhysicsGuy]

Yes. Some data is transferred using PSK phase shift keying

[@hmabboud]

@@ChrisGozzardThatPhysicsGuy I mean what is it’s application in real life.

[@ChrisGozzardThatPhysicsGuy]

@@hmabboud transferring data in real life... ?

[@hmabboud]

how to know and look , phase angle is 1/5 of wavelength , I am little confused on it

i think he just assumed but i guess in the exam, they would tell you

[@sunildinga836]

How to measure path or phase diff between two waves by taking whole wave or one crest & trough

[@ChrisGozzardThatPhysicsGuy]

The distance between the two waves peaks divided by the wavelength distance then multiply by 360 for degrees or 2π for your answer to be in Radians..

[@ronitmandal7301]

It's that little girl with that sweet voice your daughter

[@ragunanthan787]

good explanation

[@ahmedshendu2044]

what is phase diffrence of loop stationary wave ? plzz any one reply fast

[@ahmedshendu2044]

pi or zero which any one who know?

[@ChrisGozzardThatPhysicsGuy]

The whole loop of a stationary wave is in phase - there for zero.The next loop is pi radians out of phase with it.

[@creed8034]

Thats mad bro

[@ChrisGozzardThatPhysicsGuy]

Thats mad comment bro

[@girirajkashyap2912]

Does phase difference depending on size of waves

[@ChrisGozzardThatPhysicsGuy]

No. independent of amplitude.

[@saverarizwan1847]

How do u know it's 1/5wavelength??

[@ChrisGozzardThatPhysicsGuy]

Because one wave is 1/5 of a wavelength ahead.

[@beingstudious9300]

Sir plsss tell how is blue wave ahead of red wave?

[@ChrisGozzardThatPhysicsGuy]

Just an example

do we use the same method to find the phase difference between two points in a single wave

Yes. Should work as long as the points are less than a wavelength apart from each other.

[@gojeta1999]

I think theres an error here, plz correct me if im wrong. Is 1/5 lambda not the path difference and the result after in radians and degrees is the phase difference

[@ChrisGozzardThatPhysicsGuy]

hmm.. no I think I am correct. path difference occurs when you have two sources.

[@maradadharmaraju7617]

How did u say that wavelength=180 degrees??

[@ChrisGozzardThatPhysicsGuy]

!?

[@nardinadel5121]

does the examiner mention the phase difference in the exam or I might be asked to calculate it ??

[@ChrisGozzardThatPhysicsGuy]

Yes. It can come up.

[@ka-im5nd]

Either can happen. I'm doing A level now, but I did phase difference in gcse as well and the questions on this topic are similar. Sometimes you might get a question where they give you the phase difference and you have to use it to work something else out. Sometimes you'll get given two waves and asked to work out the phase difference from them.

[@abcdefgh-uu6rz]

good job!

[@ChrisGozzardThatPhysicsGuy]

+ale ale Thanks so much! Glad the video helped.

[@nurain144]

why was 1/5 lambda divided by 1?

[@lamuu5006]

idk but it makes no difference, you dont need to, but what i am guessing is that the 1 is a "whole" wavelength, and 1/5 is a fraction of it ??? i am 2 years late >.>

why measure with degree instead of time?

[@ChrisGozzardThatPhysicsGuy]

360 degrees is a complete circle and a complete wave can be thought of as different sections of a circle.
