No its not In phase if any term is negative and other is positive then the wave travels in positive direction ...OK . Its not necessary that x variable sign should only change . We can change sign for t variable also .

Okk sir
Rarer medium mtlb jis medium me km molecule ya particles ho
Aur denser mtlb comparatively usme zyada molecules ho
Jaise air rarer h aur water denser
Air rarer glass denser

At 17:00 phase of incident wave is wt-kx. And phase of reflected wave is wt+kx+π . .hence phase difference is wt+kx+π-wt+kx which is equal to 2kx+π
Hello sir ji... and thank you so much..
Thank you sir aap se physics padne ke baad physics bahut easy lagti hai..
Sir Dil se dhanyavaad apka. Mock test Mai 3 questions ISI topic se related Aaye the 70-80 rank is 47 minute ki video ne badha Di 🙏🙏🙏
Sir *aap* Bahoot achaa padaatee hooooo 😀 😀
Aayush u r absolutely right
I need a heart from your channel ...Ap ki vjha se mery physics teacher ne mjy genius ka naam dia h 😅😄
sir the sound effects which you create are more interesting and makes us easy to imagine then others mere animations.......you are great sir!!!!!
Sir aapke subscribers bohut jaldi bar rha hai.. WOW 🔥,..10 million bohut jaldi ho jay ga,🤩🤩
Are bhai logon ,At 21:57 ,fixed end mein negative sign to 4x ke aage aana chayie tha... To Yreflected=2Sin(-4x-8t+π)=-2Sin(-4x-8t)=-2Sin(-(4x+8t))=+2Sin(4x+8t) hoga????
Yes😊
Yes I think
Sirji u rocks Koi Inna acha kese padha skta h !😇
Ouff!!! Aaz mai phir se late hou
Aaz mai phir se late kar di comments krne mai lagta hai mujhe sir ka heart kabhi nhi milega 😣
Mil gya

Salute to physics wallah
Very Long question but Most Important Question at 37:46
Your way of teaching is absolutely excellent😗😗😁it reduces my all tension....😊😊
at 23:04 the sign of k will change sir not t i think. Anyone tell me weather i'm right or wrong?
Sir is lecture me last ke question me and uske pehle vale concept me aapne direction ke liye(wt) ka sighn change kiya hai jbki (kx) ka sighn change hota hai aur starting me shi kiya h aapne kx ka sighn change kiya... So correct it by pinning your comment on the top of comments.. Thank you sir😁😁
Thank you so much Guruji ✌

Sir physics mai hone wala ek chamtkar ho aap..... Agar god ne mujhe koi gift diya hai to wo gift ho aap
Though I dont know Hindi...I can understand this so easily with the way you teaching sir...thank you so much❤️
Sir is like the PewDiePie of educational channels , it's just him against all these unacademy , vedantu ,etc.. which are huge enterprices and made online education a business. Here's a guy single handedly taking on them all .
Sir Jab friction pa F limiting ki Value applied force k sath equal ho jata ha tab body ka situation kaisa hoga???
I think the body is at rest and Friction force F limiting k baraber ho jayaga???
Am I right sir........🙏🙏🙏🙏 pls replay me sir....
Right
@@PhysicsWallah Okk sir thanks
@@PhysicsWallah thanks sir for giving your responses to our precious comments and doubts even when u lack time
Congratulation for 2M subscribers
Sir 15:40 reflected wave equation must be Asin(wt - kx) as the direction of wave traveling gets opposite to the incident wave which was Asin(wt + kx).......I am saying only after referring to H.C. Verma book....
Off good!!! I was searching for this comment
Your the best ❤❤ sirrr
23:43 adding a time stamp
Sir binna dekhe maine apki vedio ko like kiya.. Thank you.. Sir u r great 😊😊😊😊
Sir a humble request :: SHM me damped SHM and force oscillation and resonance topic ke video Bana dijiye....HCV and NCert dono me hai...plzz 😭😭😭
Haan sir SHM me damped aur force oscillation ke vedio bhi bna dijiye sir ji please 🙏🙏😭😭
Jee aur jee advance me nahi aata vo topoc bas neet ka liya hai
Ya sir... Plz make video on these topics....
Sir ap hamare liya kisi god se kam nahi ha. Ap bohut achea se parate ho. Thank you so much
21:35 ,sir x=0 ka kya meaning h question me?
I thank my friend in my coaching institute jisne aapka channel recommend kiya tha. Tab sooja nahi mujhe ki mere physics ke score kam hote aur concepts kharab hote, toh aapke videos dekhne se bohot help milega. Feel karna toh door ki baat, mai last year kuch nahi samjhi. I am a NEET aspirant. Ek hi saal hai so I am strengthening my 11th physics from your videos sir. I am eternally grateful to you ki aap humey concepts ko feel karaate hain and also to that friend of mine jisne itna pyaara channel recommend kiya. Ab umeed hai :)
Did you Qualify NEET ?????
