A flexible steel cable of total length 'L' and mass per unit length H hangs vertically (under it's own weight) from a support at upper end. If transverse pulse starts to move down in the wire from its support. The ratio of acceleration of the pulse at distance L/4 from the support end to the acceleration of the of the pulse at distance L/2 from the support end K:1 then the value of K is
