How was the paper guys ?
aisa lagta hai ki sirf ek hi question me dispute hai aur wo hai Cooker wala. Baaki lagbhag vision ka sahi hai keys with explanation( Indus hata ke)
Indus wale ka source Khullar me confirm Sutlej hai jo Shabbir sir ne bhi confirm kiya hai apne answer keys me.
Baaki toh discussions ka koi end hi nahi hai.
@BhallaRobert at 82.7 how hopeful are you? Bcz I am almost same as well...considering every doubtful wrong which in my case are cooker, epf, co smelter, state definition, federal, 14vs32 and virus culture.

Don't know what is settled opinion
Maine bi exam me yehi sochke galat kiya ki its different in different mediums. But then light bends also when it travels from one medium to other.. ( Rarer - Denser)

Led wale q me mujhe laga ki 360 degree hona ek light ka advantage hota hoga
so i considered statement A wrong as govt is promoting led lights, so it has to advantageous right??
Ab bahar aake pata chala ki being 360 deg is not advantageous.. there is not of energy wasted in 360 deg light.
Sothe intention was right but execution was wrongcozlack of knowledge.Ab amazon se 360 deg light dhundke koi fayda nai..

Astronomical distances pe light bends due to gravity. Gravitational lensing kehte hain is effect ko.
I had the same doubt in exam. Dono hi option galat hain. But I ended up eliminating ye upar wala option due to above reason.
