Frequency is the function of density $(\rho )$, length $(a)$ and surface tension $(T)$. Then its value is
$k{\rho ^{1/2}}{a^{3/2}}{\bf{/}}\sqrt T $
$k{\rho ^{3/2}}{a^{3/2}}/\sqrt T $
$k{\rho ^{1/2}}{a^{3/2}}/{T^{3/4}}$
$k{\rho ^{1/2}}{a^{1/2}}/{T^{3/2}}$
Frequency is the function of density $(\rho )$, length $(a)$ and surface tension $(T)$. Then its value is
Let $n = k{\rho ^a}{a^b}{T^c}$ where $[\rho ] = [M{L^{ - 3}}],\;[a] = [L]$ and $[T] = [M{T^{ - 2}}]$
Comparing both sides, we get
$a = \frac{1}{2},\,b = \frac{3}{2}$ and $c = \frac{{ - 1}}{2}$
$\eta = \frac{{k{\rho ^{1/2}}{a^{3/2}}}}{{\sqrt T }}$
