This is again incident on the first wire, having for a

This process may be continued. The successive waves of 

 reflexion form a geometric series of common ratio

The subsequent reduction indicates that in general, with a 

 frequency of the magnitude dealt with in this ] taper, this 

 series is convergent. The effect inside the second wire, of a
