Thank you mam, it's really helpful for me. Your Explanation is simple and cleared. I understand it better , because of your lecture. Thank you mam , Wish you the best 🙏.
ma'am thank you for clearing the topics soo good but at the equation of group velocity you forgot to add '2' in the beginning of the equation of group velocity as per the trigonometric identity.
mam in exam if the question comes as find out the relation between Vg,Vp and c in that we need particle velocity =group velocity ,so do we need to derive it or directly we can say we know that....
hi mam i have a small question regarding group velocity can you please explain it. A wavemaker generates two groups of waves in a wave flume. The first group has a wave period of 1.2𝑠, while the second group has a period of 2.9𝑠. The water depth in the flume is 0.9𝑚. After generation of the 1.2𝑠 wave group, the wavemaker is stopped for 12𝑠 before the 2.9𝑠 wave group is generated. How far down the flume will the second wave group catch up with the first wave group.
Prism is an example of dispersive medium. Because when you pass white light through the prism , it gets splitted in to seven colours. Air is a non dispersive medium for white light .because in air you are not able to see all colours before the light passes through the prism.grp velocity and phase velocity of white light is equal in air medium . So dispersion doesn't occurs in air for white light. Where ever you see in a given medium grp and phase velocity for any thing "like light or for a particle" then that given medium is non dispersive for that particular particle or light.. In prism the grp and phase velocity for white light is not same . So you get dispersion. So prism is a dispersive medium for white light.
Holy, crap. I'm just 5 mins in and I've learned more than in an entire semester of Modern Physics in my uni.
Thank you so much
Thank you so much maaam i was struggling with this topic and was not able to understand this from so many teacher and u explained it in this easy way
🙏

Thanku mam , watching from uttarakhand 🙌🙌
I'm North India student mam , ur lectures are very helpful
Thank you Rupendra
@@physicsjessy7746 welcome mam , ARE YOU ON OTHER SOCIAL MEDIA PLATFORMS? PLS TELL
No
At 12th minute, on the RHS, 2 should there.
wonderful teaching
maam love your videos they are tooo good.... please make more... much loveeee
Thank you. Best wishes
Amazing explanation.. ♥️
🙏

Yes, you are right, Thank you
Thank you so much mam you explained it clearly
please mam bless me with good luck for my sem exams
🙏Best wishes dear Bhushan. God bless you 🙌
Awesome
mam please add the video for the 3d box also
Nice explanation 👌👌
thank you maam literal life saver
Thank you too
Excellent madam
Super class mam .expecting more classes
Thank you
Thanku Miss...Good lecture
What are the velocity of the waves? Are they all of the same? velocity. How do we get the wave velocity?
Anybody can answer, I will appreciate it.
my mam🤩
🙏

If it is short answer type qn, you can write.
@@physicsjessy7746 ohk mam got it thanks 😊
Pls Give some model questions in QM.

Wave velocity is more than the particle velocity. Yaanai varum pinne. Mani osai varum munne
What is h cross known as?
h cross is h divided by 2 pi. It is a modified form of Planck's constant
Ok madam
Its the reduced plank's constant
At what position constructive and destructive interfance take place?
@Casey Ronald yup, have been using instaflixxer for since november myself :D
Ma'am is prism an eg of non dispersive medium? If yes....how? Please help

Thankyou maam
Thank you mam
Thank you too
Thank you sooo much mam... 😊😊😊😊
Inside wavepacket what interfance will take place?maam
Constructive

Thankyou mam
