Optical fibres, Total Internal Reflection, Acceptance Angle, Acceptance Cone, Numerical Aperture 

I thought it was my problem understanding optics. Now i understand it's the problem of my teachers🙂

Thank you ma'am!! You're the best.

Thanks a lot mam.... easiest explanation❤

Best explanation ma'am ❣️ greetings from jharkhand

Thanks for this crystal clear explanation

thank you so much ma'am

very good explaination mam

Nice explaination mam

hello ma'am, i came across your videos today itself and i understood optical fiber clearly. i have my exams the next week, can you please do lectures on modern physics and quantum mechanics?? thank you ma'am!

Thank you madam

Thank you mam❤️

Good afternoon mam mam i have watched many videos which was good to understand the topics clearly ..... Similarly can u make some topics on [ HE-NE LASER, ND:YAG LASER, SEMICONDUCTOR LASER,APPLICATION OF LASER-HOLOGRAPHY ]. which are not there in the playlist of laser.

Thankyou❤ so much mam helpful video

Superb explanation mam

Nice class ma'am...👍

super explanation mam 🙏🙏 thank u mam

Nice 🙂 explaination

Ma'am, What is the difference between single mode and multimode optical fibres?

U are super

very nice class

Thank you Mam😍😍

thank you

Plz explain acceptance angle I can't understand With exaple

succint

Mam plz come to our clg

T

Malayalam parayoo

Derive an expression for acceptance angle? Deduce numerical aperture of optical fiber? e question ki answer mam pls

😅😅😅😅😅

Thank you mam🙏🙏

Thoda hindi ka bhi use kijiye madam Channel aur jldi grow krega

Unsatisfied mam

thank you madam
