Concept huwa crystal clear ! Thank you mam
Hi
Mam I am from Ujjain ( m.p) I don't know how I explain my emotions because I don't understand physics in my scl but your lecture provide me more confidence...😊😊 Thank you so much...
at 48:02 frequency is replaced with wavelength I hope you would correct it ... Happy to Help
Tip to learn EM waves spectrum Reading: radio waves Maths: microwaves Is: infrared Very: visible Useful: ultraviolet Xample: xrays Geometry: gamma rays Pls like😊
Like krdia h
Guys like whose concept is crystal clear🎉😅❤😂

47:57 Mam In the screen written wavelength. So, correct it to frequency range
I waited for your video n now finally it came thank u so so so much mam ur video is the only wayi understand 🥰
My dear juniors follow roshni mam lectures and make notes they help me lot in board exam some puestion are come directly from these lectures....❤❤ thank you very much mam

May u achieve heights of success,thanku for such a wonderful lecture ❤️
Finally...tq ma'am 😊
Thanks a lot ma'am 🙏🙏
Thank you soo much❤
Where can I get the notes of this chapter ?
Have a confidence😊☺
tip to remember EMW spectrum Gadi- Gamma ray X- X-ray U- Ultravoilet light V- Visible light In- Infrared light My- Microwaves Range- Radiowaves
Basic idea of displacement current. Electromagnetic waves, their characteristics, their transverse nature (delete only about ether) (qualitative ideas only). Electromagnetic spectrum (radio waves, micro waves, infrared visible, ultraviolet, X- rays, gamma rays, elementary facts of electromagnetic waves and their uses.
Sir hum puri tarah se taiyar he pura Josh laga denge Jai Hind sir ❤❤
Ma'am I think you might have forgotten to attach the pdf of notes and questions of electromagnetic waves... Ma'am, kindly please attach it 🙏🏻..Thank you 😊
Good concept ❤❤❤❤❤
Mam please make the video of whole class 11 and 12 th physics or chemistry in one shot ,one shot help us alot during exam of neet
Mam you are the best teacher in my full life....😊
Thank you mam for this amazing lecture❤❤
Thanks mam ..it was very helpful
All the best for tomorrow physics 👍👍
Thankyou so much mam ❤ so smoothly explained each and every topic ❤

Very nice explanation Mam 🙏
Thankyou so much ma'am ❤️❤️
You are great ma'am 🤗🤗❤
Ma'am I was very afraid of physics but when I saw your videos a magical spirit appeared inside me! Now physics is my fav subject and I'm going to pursue Quantum physics after 12th. Thankyou so much Ma'am you changed my life completely!!🙏🏻

Thanks you mam for this lesson
Thankyou so much mam❤️
Mam agar magnetic field inward hota hai to current clockwise hota hai fir lenzs law ke according agar magnetic field inward hota hai to oppose krne ke liye current anti clockwise jata hai. To current clockwise jata hai ya anticlock wise??😢😢
Too good explanation Madam.Thank you very much
