Example 2: A hot blackbody emits energy at a speed of 16 J m-2 s-1 and its most intense radiation corresponds to 20,000 Å. If the temperature of this body rises further and its most intense radiation is equal to 10,000 Å, then you will find the value of the radiated energy in Jm-2 s-1. पृथ्वी पर A0 के गोले से गुजरने वाली ऊर्जा, सूर्य और पृथ्वी के मध्य दूरी और गोले के के म म के म के म गोले के म म के म म ��्य े प्रत्येक वर्ग मीटर से गुजरने वाली ऊर्जा निम्न समीकरण द्वारा दी जाती है Example: An emissivity body (e = 0.75), the area of 300 cm2 and the temperature of 227 ºC must be maintained in a room at a temperature of 27 ºC. Calculate the initial value of the net power delivered by the body. = (0.75) (5.67 × 10-8 W/m2 – k4) (300 × 10-4 m2) × [(500 K)4 – (300 K)4] The total radiated power per unit area over all wavelengths of a blackbody can be obtained by incorporating the Plank radiation formula. Thus, the radiated power per unit area is a function of the wavelength: Similarly, one can find the effective temperature TE of the Earth by balancing the energy received from the Sun and the energy radiated from the Earth by the approximation of the black body. The power emitted by the Sun ES, is given by the following equation: Save my name, email address and website in this browser for the next time I comment. “where e = emissivity (which is equal to the absorption force) between 0 and 1.
