Sir I am requesting you from my heart 🤕 Plz tell me why we represent light as ray??? 😭😥 explain this doubt. I have seen most of teacher while teaching lenses.say light ray is entering in lens but light ray is path of light.how can we represent light by its path.
Bhai sawal angrezi me poocha to Hindi me kyu deta jawab, Mere kehne ka matlab yeh hai ki jab tum padhte hona ray idher se udhar gayi, hum woh sirf ek ray ke bare me padhte hai coz Puri beam ke liye padhna mushkilhota hai, I mean, dekho hum different diff, origins se lightray ko incident krwate hai so that hum unka behaviour padh paye, then hum usko generalise krte hai.
