Two spherical stars A and B emit blackbody radiation. The radius of A is 400 times that of B and A emits $$10^4$$ times the power emitted from B. The ratio $$\left(\frac{\lambda_A}{\lambda_B}\right)$$ of their wavelengths $$\lambda_A$$ and $$\lambda_B$$ at which the peaks occurin their respective radiation curves is
