Yaar, concave mirror ke liye tumhe sirf do important rays chahiye: ek parallel to principal axis, jo focus se reflect hoga, aur dusra jo focus se jaata hoye aaye, woh parallel reflect hoga! Saare six positions ka toh bhai, yaad hai? Image ulti, seedhi, bade ya chhote size ki banegi... par practical mein hum toh bus projector aur headlight ka diagram banate hai polytechnic lab mein!
Hamare yahaan toh sirf theory padhte hai, lekin mera real learning aata hai gym ke glass mein logo ko dekh ke – wohi actual reflection samajh aata hai, ki confidence kaise badhta hai!
