Angular distribution of radiated power is-
 

\mathrm{\frac{d P}{d \Omega}=\frac{\omega^4 P_0^2 \sin ^2 \theta}{32 \pi^2 \epsilon_0 c^3}}
\mathrm{but, P=\int \frac{d P}{d \Omega} d \Omega with d \Omega=\sin \theta d \theta d \phi }
\mathrm{we get P=\frac{\omega^4 p_0^2}{12 \pi \epsilon_0 c^3} \Rightarrow \underline{P \alpha \omega^4} Ans }
