7.1e Ex3 MJ20 P12 Q22 Phase Difference Between Waves | AS | Cambridge A Level 9702 Physics

[@zoyajunaid6351]

You explained it so well, thank you so much for this!

[@nabeeharehman1140]

choosing a reference point was confusing for me. so what I do is find where both waves' crests are starting. find the difference between the start points of crests and then divide it over the whole time period. then use the ratio to find the angle. if the answer is not in the options, subtract from 360.

[@Ibrahim.Sami.7]

Thanks..

[@clairr4]

by “the whole time period” u mean 1.2?

[@nabeeharehman1140]

​@@clairr4 no, the time taken for one complete wave

[@aimanesennouni2644]

​@@nabeeharehman1140 Hi Nabeeha, can you please reply, i need help and I hoope you can help 🙏

[@Cringe-freeContent]

aint getting the correct ans for this ques using ur method.... it might be wrong or work in specific cases only

[@Hareemfatima-pe9xo]

U r funny funny teacher, i like your way of speaking

[@gknkrnkjgjugjrgjrng]

ur name is haram

[@coffinman4527]

this is helping a lot when revising for my yr 12 mocks thank you 😭

[@malikabd2902]

I literally love you for this calculating phase difference was long and difficult af cuz i was doing it by fractions of wave cycles and your method is so much easier thank you

[@jasonakonnor9377]

thank you for explaining this, took me 2 years to learn it myself but you explained it to me in 5 minutes lol

[@glimmerpearl115]

Thank you now I understood this.

[@asifalamjoy9530]

I should have paid you my tuition fees instead of paying those morons who made this wonderful concept a nightmare for me. God Bless You ma'am.

Woman saved my day thank u

[@tacticalhuddy3614]

When you work with the Angle covered per division [360/20] time the no. of divisions in the phase difference makes it a lot easier. Nice job though..

[@cl.5974]

It is very good explaining Thank you so much. Hopefully, I you can post more videos that are related to Phase array antennas.

[@eshalshoaib5923]

Excellent explanation...thank you

[@Abdul988-u8r]

thank you so muuch that was so helpful

[@mubaris.s]

dont stop uploading 😢

[@shifarizwan8338]

How to choose reference point please explain

[@ETphysics]

Can pick highest point, the lowst point, or the equilibrium point.

[@lbrandon1227]

Thank you❤

[@Kanzan11]

thank youuuuuuuu soo much

[@muhammadmuhidkhan586]

Thank you for making these videos it helps us students a lot

[@roselinahthembi1493]

Where did u get 0.3?

[@vrchville]

And what if both 135 and 225 where given?😩

[@karel486]

This is nice

[@shabnamkavakeb648]

very helpful video. thank you

[@itlover3721]

damnn..i love your explanations!
