XI-14-3 Waves Reflection and superposition(2015) Pradeep Kshetrapal Physics

[@harshitboss]

The way you teach is awesome.

[@mtaneesh1411]

Sir you are the best physics teacher!!

[@AuthenticEnglish]

M Taneesh right bro

[@AuthenticEnglish]

Are you preparing for medical?

[@mtaneesh1411]

Authentic English nope

[@Rohit-tz6gs]

Check LIGHTHOUSE....den come here agn and take ur statement back.

[@ushabansal1008]

sir 21:42 pr aapne konsi eq.likhi hia or kyooo? jisse aapne edit kiya hai?

[@InderDev-lz3zk]

Yess sir iis it important😦😦

[@harshdubey4037]

How lucky are those students sitting over there.....

[@alijandan9369]

name of book plese which is he using..??

[@nirujoginarsimhanaidu9475]

@@alijandan9369 ncert 11 physics

[@lathapurushotham6345]

is rarer medium similar to free boundary

[@alijandan9369]

sir what the book you are using ..???

[@dadasahebbhavar5429]

Sir you teach very well. ... you are best teacher. ......thank you very much sir

[@mohdsam3900]

after reflection from rigid body amplitude decreses then why should u take same amplitude in solving it by principle of superposition. ..?????

[@nidhivijay5530]

It depends if it's perfectly rigid body or partially rigid body. I'm prefect rigid the reflected wave would differ by incident wave by only a phase difference and nothing else everything else is constant

[@anishabisht4213]

Why does frequency remains same in all mediums whereas wavelength changes? Jyada density vale medium me to no of cycles ek sec me kam honi chahiye

[@vishnulokeshknowledgeplusa424]

denser medium mai amplitude kam ho jata hai par frequency bahi rahti hai ♥♥♥♥

IS ANY ONE WHO IS WATCHING THIS in 2022

[@bellachaio1133]

sir if medium is change some energy must be change as u say . so wave on 2nd medium get low energy why frequency. shouldn't be change ?

[@nidhivijay5530]

Check last video

[@muzammilshah3045]

frequency is independent of medium it only depends on time more the frequency less time and vice versa

[@ritikthakur5844]

Speed of wave increases in rarer medium. So, I'm confused with the following data: Speed of sound in Air = 331 m/s While speed of sound in Aluminium = 6420 m/s (I'm assuming Air to be a rarer medium as compared to Aluminium)

[@simrat.0]

Ritik Thakur please go to the previous video of waves see end portion

[@krishnanegi9992]

speed wve dcrece in rerer medium.

[@rayquazaregigigas]

Einstein Admirer. Speed of sound in a medium is directly proportional to how fast the particles oscillate and give the energy to the next particle. And denser rarer medium refers to resistance offered by the medium. Hope you understood

[@anjurani2815]

For sound wave.. Air is denser medium and solid are rarer one. And reverse is true for light.

[@nidhivijay5530]

Density is one of the factor for the change in speed but elasticity is the dominant factor..... So we can use denser or rarer for comparing only if the elasticity does not have a big difference

[@shaileshgautam8491]

sir how is the phase differnce is pie

[@bhawanakapoor9097]

Thank you sir

[@akshayagrawal2510]

Nice one thnks sir

sir ...... appp kisi bhi question ka ans dete hi nhn hn..... mn me apse kitne qs kiye hn but no reply.... sir plZ batae k optical center se pass hone wali ray .... bend kyun nhn hoti ..... plzzz :-)..... I want to clear it plzzz.... nd I need ur help ....... plzzz sir ....

+Pradeep Kshetrapal .... sir .... mn app ke purane lectures dekh rha hun ..... and mn apne topic k accordingly apne qs krta hun ....... sorry sir agar apko koe problem ha to ....

+Pradeep Kshetrapal thnk u ... sir ...... to mn appse qs kar sakta hun..... according to my topic..... :-) ..... u r the best sir..... bundles of thnks..... sir .....

[@bheeshamkhatri4541]

+Pradeep Kshetrapal sir plzzz .... ap mujhe ye bhi bta dein k parallel surfaces p bend kyun nhn hoti .... plzzz ..... sir plzzz mere iss concept ko clear kr dein..... plzzz .... I need ur help... :-) .....

[@adilh3908]

Sir where this lectures takes place? ?

[@sujatabanerjee7880]

korba (CG)

[@VikashKumar-ww3nz]

optical centre ka normal wave k parallel hota h........ so incidence angle zero hua so reflection angle b zero hoga by laws of reflection........ solved @bheesham

[@bheeshamkhatri4541]

ye app jo mujhe bta rhe hn .... wo lenses k topic mn ha ... ?..... @vikash ... mera question lenses k bare mn ha

[@VikashKumar-ww3nz]

me b usi k bare me bta rha hun

[@shailesh5156]

👌🏻👌🏻👌🏻

[@fakharuddinkhan3604]

If wavelength decreses then time period will also be decrese,as a result frequency will increase 🤔🤔🤔🤔

[@nidhivijay5530]

Nope time period at would remain same check out the previous video

sirrrrrrrrrrrrrrrrrrrrrrrrrr kitnaaaaaaaaaaaaaaaaaaaaaaaaaa dheereeeeeeeeeeeeeeeeeeeeeeeeee padhateeeeeeeeeeeeeeeweew ho app
