L8: Class 10th,NUMERICALS ON REFRACTIVE INDEX (OPTICAL DENSITY) TIPS & TRICKS

[@Kathan_]

Sir your guide may have saved me some marks in my exam thank you Edit- sir you saved my 3 marks

[@kyrilgaming1713]

Best teaching and sweet voice sir.Sir you made my year

Second account se comment kar liya

[@souravbeyblade557]

Yes you are right

[@feedbacker.70]

Your actually one of the most hardworking and effort giving teacher in this topic refractive index. You're also explaining the hard problems unlike others, who are just explaining the easy question in an extended manner, trying to appear as if it was the hardest.

[@himanshushukla897]

Sir thankyou refractive index ke question ne mujhe pure sal pareshan kiya lekin aapne samjhaya ek baar mai hi Sekh gya thank you so so much sir

[@PREM-SINGH-BANA-0328]

Thanks bro brooooooo When you say *bass itne easy easy hii board me ask honge * (I so happy)0 I am finding numerical on refractive index for a about 4 5 hours today (27 March) And so I finally get this

[@raamgautam]

O bhai, 4 hrs 😂

But 4 hrs in searching part is truly incredible 😂

Sir in 2nd question change is equal to initial-final So 3*10⁸-2*10⁸ karenge to 1'10¹⁶ aa jayega.sir PLZZ clear my doubt🙏🙏

[@guess8569]

si questions were easy but your exaplanation is like AWESOME!!!!

Thank you so much sir, all my doubts got cleared after watching this video 👌🙏... You are the best 👍💯 and btw your voice is as sweet as sugar 🌝🪐☺😅

N21=N1/N2 hoga and the refractive index of water with request to glass is N water-glass=Nglass/Nwater asa aiga

[@Shivamvashistha92]

Bchche ye galat h..... 🙏 n21=v1/v2 hota hai....aur n21=n2/n1 hota h....both formulas are different .....dont get confused

question(1)-Ans - Refractive index of glass with respect to water= R.I of Glass/R.I of Water =3/2 × 3/4 =9/8

[@reenameena3645]

Please solve this problem your answer= 8/9

[@Shivamvashistha92]

Beta....watch again.... I solved both RI separately.... My ans is also 9/8.... In 2nd part

[@EkanshBhagat]

Shivam sir is one of the underated physics i found he is teaching extremely awesome not words all the best sir because of you my physics is improved🙏🙏❤❤

[@smayrabatra8281]

Sir is topic k numericals pr aur bhi videos bnao and I liked ur way of teaching and subscribed ur channel too🤗🤗

[@anshumandwivedi6918]

Sir .. kindly note this error 🙂 in the second numerical you subtracted final speed from initial speed i.e. u-v thus the answer was positive if you subtract initial speed from final speed i.e. v-u the answer would be negative other than that whole video was a lot helpful to me thank you sir ☺️

[@Shivamvashistha92]

Yes.... I mentioned in the video that answer should be negative because speed is decreasing but we are just showing change.....so sign mention karne ki jrurat nai h 👍

[@tarungupta1867]

Thank u sir you explained very well and you deserve millions or subscriber

[@piyushasangale5403]

Thank you so much sir ☺️ Have exam tomorrow 😀 Feeling pretty confident after the video......

[@shrawanichougule85]

Sir you are soo cuet

[@dhruvgupta8180]

Really sir today i understood these type of numericals .❤️❤️❤️❤️ And sir aapki voice bahut pyari h😂

[@sakshampandey-iq4sz]

sir in the percentage question the change will come in minus because the change in speed will be final speed - initial speed that is 2*10^8-3*10^8 that will be -1*10^8

[@Shivamvashistha92]

Yes.....correct.....I only mentioned the magnitude

[@karanjindal5608]

video begins at 1:05 one request : i gave the time stamp because when i was in hirry there was someone arround me who gave the time stamp of another video , so the people using my given time stamp do make sure that you do it in the comment sections of every nice video

Sir last question's answer will be 2.66x10^(-8) sec btw i learned about the percentage type of question thanks a lot sir ji☺

[@elisiqn5639]

Yes i was having same doubt but my teacher told me when a number is repeatedly terminating than add 1 to it. So instead of writing 2.6666 and so on just add 2.6+1 that is 2.67.
