[@SanthoshVijayakumar-s5u]

very straight forward and clear cut explanation, thankyou mam

[@physicsjessy7746]

Thank you too. All tge best🙏

[@FearlessLife-qm3jb]

Best explaination ever mam

[@archivvithlani6610]

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

[@physicsjessy7746]

Thank you so much 🙏

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

[@afbkhn3721]

ma'am you explanation and teaching way is very good

[@physicsjessy7746]

[@yasithperera7687]

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

[@physicsjessy7746]

Thank you 🙏

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

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

thankyou maam

[@physicsjessy7746]

Thank you so much

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]
