N2/N1 cannot be called as the absolute RI for all cases as it is applicable only when one of the pair of media is vacuum( this formula is mostly used as relative RI). The formula for absolute RI is n= c/v
Really sir your teaching way is amazing ..... I understand whole chapter in half an hour ❤️❤️❤️ thanks a lot sir for giving this outstanding lecture to us ❤️❤️❤️❤️🥰🥰🥰...
tysm for uploading this, this saves so much time and energy and you uploaded it right around the time I needed this revision lesson the most. Thank you so much Edumantra.
After all you helping us too much by upload this fastest revision series....... thank you very much ... sir you are best teacher in all over India for teaching science ....
Sir actually I'm in class 12 but when I see ur channel sometime I get emotional cuz when I was in class 10 u was my favourite teacher I miss ur teaching style sir ......at last love you sir 💕

Sir a nice recap video overall , lens formuale and mirror formuale is wrong , u in replcaed by v and v is replcaed by u for mirror it should be 1/f = 1/v + 1/u for lens it should be 1/f = 1/v - 1/u

Hello sir,
Mirror Formula 1/F = 1/V + 1/U HOGA
YA
1/F = 1/U +1/V HOGA
1/v + 1/u = 1/f
Sir can you please take nervous system revision
❤
Sir the lens formula that you have written was wrong
It should be 1/f=1/v-1/u
Ready h sir ab paper faad denge
I am revising this on 5am on my sci board exam 😂
I watch this video before 1 hours in my exam😅
Sir next video how do organisms reproduce plzzzz 🙏
Thank you sir this will help me to revise the ch once again... Because tomorrow is my 2 preboard 😊😊
Thanks sir for this revision series👍👍🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Nice sir mja a gya ch bilkul dimag pr attack kra hai

Sir a nice recap video overall ,
lens formuale and mirror formuale is wrong , u in replcaed by v and v is replcaed by u
for mirror it should be 1/f = 1/v + 1/u
for lens it should be 1/f = 1/v - 1/u
