+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.Intensity = power/area se hi derived hai
we good?
I = Power/area = Energy / time x area
I = ( e E0^2) /2 area x time
whats next?

This can be mathematically proved from wave eqn
we good?
yes
