An ideal blackbody radiator initially emits a total power \(P_0\) at an absolute temperature \(T_0\), with its emission spectrum peaking at wavelength \(\lambda_0\). The blackbody is then heated without changing its surface area until its total radiated power increases to \(2P_0\). Which of the following is the best estimate of the percentage change in the peak emission wavelength \(\lambda_{\text{max}}\)?
