A star can be approximated to a black body mostly constituted of gas with a surface...
A black body has an effective surface temperature of 450°C. Determine: (a) The total radiation energy (W/m2) that can be emitted by the black body (b) Determine total radiation energy (W/m%) that can be emitted by the black body within the 5-50 um wavelength region (c) The spectral blackbody emissive power of the black body at a wavelength of 10 um. 12
8. A black body has an effective surface temperature of 450°C. Determine: (a) The total radiation energy (W/m²) that can be emitted by the black body (b) Determine total radiation energy (W/m²) that can be emitted by the black body within the 5-50 um wavelength region (c) The spectral blackbody emissive power of the black body at a wavelength of 10 um.
3. The sun can be approximated as a spherical black body with a surface temperature of 5762 K. The irradiation from the sun, as measured by a satellite in earth orbit, is 1353 W/m2. The distance from the earth to the sun is approximately 1.5 x 1011 m. Assuming that the sun radiates evenly in all directions, estimate the diameter of the sun.
Calculus Problem, l'Hopital rule. Please see the attached picture. I know the function is undetermined with the limitation of 0+, but even after I have applied l'hopital rule to derivative the numerator and denominator, I still find the function is undetermined as the λ always has a negative power, so I cannot substitute λ=0 into the equation. Please help me. Really appreciated! A blackbody system is a system that absorbs any radiation it encounters. An example would be a perfectly...
