The power radiated by a black body is P and it radiates maximum energy at wavelength, λ_0. If the temperature of the black body is now changed so that it radiates maximum energy at wavelength 34λ_0, the power radiated by it becomes nP. The value of n…
The power radiated by a black body is P and it radiates maximum energy at wavelength, \(\lambda_0\). If the temperature of the black body is now changed so that it radiates maximum energy at wavelength \(\frac34\lambda_0\), the power radiated by it becomes nP. The value of n is
1. \(\frac34\)
2. \(\frac{256}{81}\)
3. \(\frac43\)
4. \(\frac{81}{256}\)
