Consider a string..
v
transverse =
(T/m), T = tension, m = mass/unit length
and v
longitudinal =
(Y/
), Y = Young's modulus,
= density
now m = 1.A.
, A = area of cross section
= A
and Y = (T/A)/strain
So v
transverse =
{T/(A
)}
and v
longitudinal =
{T/(A.strain.
)}
So v
transverse / v
longitudinal =
strain << 1
So vtransverse << vlongitudinal.
Got it frnd... :)
