thank you very much Doc al it is as what you mentioned related to the current density for c and d the current is the same whereas in b smaller and a is even smaller than b
Sometimes we think in very difficult method when we can solve it in easier way
Thank you again and regards
Hellow every one I have small Q but I stuck on it
there is pic attached
hope to be intersting and clear to you

Homework Statement
When a wave travels through a medium, individual particles execute a periodic motion given by the equation : y = 4.0 sin[ pi/4(2 t + x/8)]
where y and x in meters and t in seconds the phase difference at any given instant are 20.0 m apart is
