Download Solution PDFसंकल्पना:
कृष्णिका के लिए स्टीफन-बोल्ट्जमान नियम का उपयोग करना:
\( E = \sigma T^4 \)
तापमान ज्ञात करने के लिए, वीन के नियम को लागू करें:
\( \lambda_{\text{max}} T = b \Rightarrow T = \frac{2890}{0.49} = 5897.96~K \)
अब गणना करें:
\( E = 5.67 \times 10^{-8} \cdot (5897.96)^4 \approx 6.86 \times 10^7~\text{W/m}^2 = 6.86 \times 10^4~\text{kW/m}^2 \)
