I think sir had explained this wrong, by mistake. Answer will be :- Microwave used in radar system, as they do not easily gets diffracted. Note:- Diffraction is phenomena in which light rays moves forward after striking in obstacles by changing their original path. But diffraction not occur in case of microwave . I hope you got understand, good luck ☺️☺️.
Sir Mai Up Board Se Hu Par Mai Aapko Pichle Saal Class 11 se Follow Kr Rha Hu and Class 11th M Mere Physics M 94 and Maths M 97 Aaye the I Hope is saal Bhi Mere Board M 95+ Aaenge. Thank you so much sir
thank u so much sir for this upcoming video iske baad ek last chapter or ray optics plz sirr ye bhi baat maan lijiye u are the best physics teacher i ever seen
47:04 sir ya wale question mein gama rays ana chahie because the frequency of Gamma rays lies to 5 into 10 raise to power 18 to 5 into 10 raise to power 22 that's why sir
Thankyou sir today is my physics paper and most of the question are similar i watch marathon video is very helpful for me. And also practice the pyq series once again thank you sir you are best teacher on youtube... 😊😊😊
I am new here. Agar mai koi pyq ki book na purchase karke bas inn questions ko hi practice karu to enough hoga ? Kyuki Sir ne book k saare questions hi cover kiye hai. Please respond.
17:17 microwaves have the longest wavelength after Radio waves. Then how are we considering it as a short wavelength?

Google pe bhi yhi answer hai kuch smjh sa ni aaya
49:01 minimum frequency - radio waves❤❤

Thank you so much sir

Truuuu
48:55
Radio waves have minimum frequency.
Completed all chapters pyq till now
Thanks sir, today is my physics paper upto ch emwaves 😅
49:24 is wala question ma lowest frequency to radio waves
47:04 sir ya wale question mein gama rays ana chahie because the frequency of Gamma rays lies to 5 into 10 raise to power 18 to 5 into 10 raise to power 22 that's why sir
Yes..
Yes bkl sala
I think in the last question the correct answer should be 1:1 coz they asked for the ratio..
57:34
Thanks sir , for wonderful pyq session.
It helped me to analyse my preparation level very well.
Thankyou sir today is my physics paper and most of the question are similar i watch marathon video is very helpful for me. And also practice the pyq series once again thank you sir you are best teacher on youtube... 😊😊😊
All the best

Yes 👍
Yes that would be enough
@@gyangaming6295 alright
Yes
start from 3:08
49 : 00 guru ji radiowave ki minimum hoti h frequently
Apne galti s microwave lilh diya shyad
sir watched your ac emi and em waves pyqs video it helped me a lot my physics mid term exam is on 17 sept 2024
Thankyou so much sir... really helpful...👍🏻👍🏻👍🏻💫
Keep watching
ray optics bhi daal dijiyega sir
pyqs
sir aapki vajah se phy mera fav. subject bn gya ha ab baki kuch krne ka mn hi nhi krta bs physics hi krta rehta hu haha
3:08-start
14:25 23:12
sir kya iss chapter ke zyadatar questions theory based hee aate hai???????????????
Tomorrow is my exam 😢
Is these pyq are enough??
I am from lakshya jee1.O
Sir please give pyq s of 😊ray optices
important Qs;-
23:33
Yashwant present sir
I have buy a guild I don't how to use please reply sir🙏😿
Sir ka ek he viedo mai fit hone ka kya raaz hqi
46:57 ANS. (gaama rays)
48:45 wrong minimum freq radiowave
Maximum hota h bro
Bas range yad karni n .. sir uspe ek short bana dijiye m bhul jata hu
31:20
Sir pyq nhi hai app pr
27:00
sir when will u drop the ray optic's pyq
with in a Week
Sir eska pdf kha sa lay
Watching one day before test😂
Thnkiuhh sir❤
Ye sirf boards ke liye h purely anyone reply
Yes.
But it also clears your basics for preparation of any competitive exams.
Thnk u sir❤
👍🏼
