Question:medium
If a black body at a temperature T radiates the maximum energy at a wavelength \(\lambda_{m}\), then to radiate the maximum energy at the wavelength \(\frac{\lambda_{m}}{3}\), its temperature should be
If a black body at a temperature T radiates the maximum energy at a wavelength \(\lambda_{m}\), then to radiate the maximum energy at the wavelength \(\frac{\lambda_{m}}{3}\), its temperature should be
Show Hint
Wien's law: \(\lambda_{\text{max}} T = \text{constant} = 2.898 \times 10^{-3} \text{ m·K}\).
