We need to paint the area of side wall where Angle of incidence would be less than Qc
Wo sab to mai samajh gaya
But question kaise karu 🥲🥲
Aise kuch karke area 4ra karne ka irada tha
Phir realise hua ki aisa koi option nahi hai 💀💀💀

Critical angle nikalo fir wo area dekho jo tir ke area k andar ayega jaha se light escape ni kr payega to jo remaining hai waha se light escape kr sakta hai wo hi required minimum area hai
Arey par wo nikalu kaise wo to batao aaega kaise ðŸ˜ðŸ˜
Tir ka angle nikal lr
Fir tujhe pata ha ki ye minimum area kuch circular banega
Trigno lagakr vo radius nikal sakta
Area aajayega
Hn bs ye step krna h
Ohhhh
Hmmmmm
But
Achcha theek hai chal karta hu 3 min
Are you familiar with that circle of illumination wala concept?
Ki matlab a fish can only see a circular portion of what's outside
Similarly now the bulb is the fish and glass is the water
Only the stuff inside that circle (in this case semicircle) can go out of the glass cube
And other stuff gets reflected.
From a visual standpoint
OHHHH SO PHIR AB WE APPLY THAT LPGIC FROM THE POONT OF TIR
OKKKKKK
THEEK HAI THEEK HAI
