very straight forward and clear cut explanation, thankyou mam

[@physicsjessy7746]

Thank you too. All tge best🙏

[@archivvithlani6610]

you remind me of a phy teacher i had 8 years ago, very nicely explained🥰

[@physicsjessy7746]

Thank you so much 🙏

[@FearlessLife-qm3jb]

Best explaination ever mam

[@mynamestgija]

Well taught the lecture ma’am ….teaching physics is an art … ur vedios on physics is reallllly realllllllllllllllly helpful

[@physicsjessy7746]

Thank you so much. All the best

[@matrixmindmaster]

thank you so much , for this wonderful explanation
🙂

you have explained it the best out of all videos on modes n dispersions i have seen n read.. very practical approach. I was confused regarding what actually are modes.. but now I am clear about it.. Thanks ... I have subscribed. I have lightwave exam in a month.. hope you upload videos on TE and TM polarization in slab waveguides as well.. Thanks

[@physicsjessy7746]

🙏🙏

[@kaavyabanerjee]

@physicsjessy7746 Will you upload the TE n TM polarization videos?

[@afbkhn3721]

ma'am you explanation and teaching way is very good

[@physicsjessy7746]

I'm watching one day before exams 😅 thank you making informative videos mam thank so much

[@somyagupta6805]

Maam your explanation are too good. I have seen your diffraction videos. Although i have my physics exam in 2 hours than i am done with this subject but still keep making these video. They will be really helpfull for the rest to come.😊😊

[@physicsjessy7746]

Thank you

[@Reddy1122]

So nice mam your teaching is veryy excelent that Btech lectures ❤🎉

[@physicsjessy7746]

Thanks a lot

[@yasithperera7687]

Thank you very much. waiting for the next content madam...

[@physicsjessy7746]

Thank you 🙏

[@kanaiyakanabar5178]

Very well explained, ma'am !

[@physicsjessy7746]

Thank you kanaiya

[@keyachandrakar2103]

Thanks a lot mam for helping ❤✨

[@physicsjessy7746]

Thank you. All the best

Mam for graded index it is skew rays. Because skew rays are follow helical path.

[@zziikiincrse2476]

A step-index fiber has a core index of refraction of n1=1.425. the cut-off angle for light entering the fiber from air is found to be 8.5 deg[for air, refractive index=1.0008]
(a) What is the numerical aperture of the fiber?
(b) What is the index of refraction of the cladding of this fiber ?
(c) If the fiber were submersed in water, what would be the new numerical aperture and cut-off angle [for water ,refractive index=1.33]
