Thank you sir..really loving all ur videos..I am in 8th standard and the book has so much detailed explanation..But all thanks to u that u explain topics easily..Hance proved: OLD IS GOLD 😊
Bending isn't necessary for refraction to take place the main thing is that If speed changes while travelling from one medium to another that is called refraction...!

My physics teacher completed refracted idex in just 5 min. This is the difference between our alakh sir and other teachers 😏😏
true
mauj kardi
That's why you wrote ' refracted index '
What's refraction?
@@siddharthakumarpal2784 Next generation humor 😆🤣🤣🤣🤣lmao
Agreed
Bending isn't necessary for refraction to take place the main thing is that If speed changes while travelling from one medium to another that is called refraction...!
