स्टीफन-बोल्ट्जमैन का नियम:
- स्टीफन-बोल्ट्जमैन के नियम के अनुसार निरपेक्ष तापमान T पर एक कृष्णिका के क्षेत्रफल A से प्रति इकाई समय में उत्सर्जित विकिरण की मात्रा तापमान की चौथी घात के सीधे आनुपातिक होती है।
⇒ Q = σbAT4
जहाँ σb = स्टीफन स्थिरांक = 5.67×10-8 W/m2 K4, A = क्षेत्रफल और T = निरपेक्ष तापमान
व्याख्या:
- ऊपर से, यह स्पष्ट है कि स्टीफन-बोल्ट्ज़मैन स्थिरांक का मान 5.67×10-8 W/m2 K4 है। अत: विकल्प 4 सही है।
