+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.A option to theek ha
C kyun?
Momentum
Same reason
Twice the force is imparted to send it back
Dekh what is pressure... It's force/area and what is force... It's change in momentum/time
Ab jab wave absorb ho raha hai uska momentum change kya hoga... (mc - 0) right ??
To usse force IA/C banega and pressure I/C banega
Ab jab wave reflect ho raha hai to change in momentum kya hoga... [mc - (-mc)] which is 2mc; because jab vo surface par hit hoga to uski velocity niche lagegi aur reflect hone ke baad uski velocity upar hogi to momentum mei -ve aayega
To usse force 2IA/C banega and pressure 2I/C banega
Are shittt
