Note for OP
+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=AW^2 se A nikalna hai
then R=2Asinkx with x=l/2
am i correct?
,rotate
this gives ans as 10^-3 m
given ans is 5 * 10^-4m
Why 2A? Wouldn't the amplitude of vibration be A only?
interfering wave eqn se 2A
Aare but
if you'll apply a = w²A in this then you'll get the desired amplitude
no need to multiply it by 2
You'll get 2A straight away
because maximum point pe Acceleration at the top most point would be w²A where A is the amplitude of the "standing wave" not the constituent waves
what
why
why doesnt my method work
Because you connected something that is not related to that question
You thought that the amplitude you're getting is on the constituent wave
but no
the amplitude you're getting is of the standing wave
hmm right i mixed up few concepts
