sir i feel myself so lucky that i m studying from a marvelous teacher like you...in ur journey of 2 years u have changed the lives of thousands of students and in upcoming years our nation's youth will salute u for sure..... can't explain my respect for u in words....
I am teacher. Since 10 years i am teaching Physics but few days before I get struck in diffraction somewhere due to the way I teach physics to those student who were happy with my teaching but suddenly presently some student are not getting feel of diffraction so I thought that lets have feel from Pande sir first. I am tremendous happy that I understood his method which is suitable for my current student. Now I am proud that I can copy his lecture style for diffraction. Hats off sir.
@@gurunathhebale2851 thec? Ya think teachers are gods or smthng? Everyone can get stuck at their job at any point of time. Even the biggest scientists can make mistakes in some important experiment.

Today is my board exam and i am watching this video and leaving this comment so that in future if someone's like this comment It will give me nostalgia of this exam fear
I came here to study wave optics and very happy when I saw there are only 8 videos but later got to know that each video has timing minimum 1 hour or maximum 2hour but sir good explanation 😊😊
1:16:05 "These sources of light doesn't marry anyone and they are very very happy" 😂😂😂😂 But I DON'T MEAN IT. Everybody has their soulmate and they will make your life an adventure with all the ups and downs.

Wrong English
Diffraction:
1) When light strikes the opaque object, it bends around the corners and enters into the shadow region forming the alternate Fringes
2) There is no sharp boundary b/w illuminated region and shadow region
3) There is a formation of central bright
4) We have to study the width of Fringes, size of Central bright and distance b/w Fringes and central bright
Between illuminated reason and dark, we observe alternative bright and dark fringes called diffraction fringes.
Hence one again proved Light is a wave.

can't explain my respect for u in words....
Basically light decides when to show wave form and when to show particle form . (Quantum mechanics ) Bhor bhaiya ne kya hi mast socha tha

This guy gonna change the edu sys 👏👏👏

I am teacher. Since 10 years i am teaching Physics but few days before I get struck in diffraction somewhere due to the way I teach physics to those student who were happy with my teaching but suddenly presently some student are not getting feel of diffraction so I thought that lets have feel from Pande sir first. I am tremendous happy that I understood his method which is suitable for my current student. Now I am proud that I can copy his lecture style for diffraction. Hats off sir.
You should not misguide the poor students... Stop teaching if you can't.
@@gurunathhebale2851 YES :P
@@gurunathhebale2851 thec? Ya think teachers are gods or smthng? Everyone can get stuck at their job at any point of time. Even the biggest scientists can make mistakes in some important experiment. Just because someone is a teacher doesn't mean that they have clarity over ALL topics. Bruh. I am just a 12th class student but I still wrote this to let you know about this.

Amazing teacher i have ever seen in my life 😘
