Intensity of radiation emitted by black body at absolute temperature Solution

Follow our step by step solution on how to calculate Intensity of radiation emitted by black body at absolute temperature?

FIRST Step Consider the formula

I b = \frac{[Stefan-BoltZ] \cdot (T^{4})}{π}

Next Step Substitute values of Variables

∴

I b = \frac{[Stefan-BoltZ] \cdot ({85K}^{4})}{π}

Next Step Substitute values of Constants

∴

I b = \frac{5.7E-8 \cdot ({85K}^{4})}{3.1416}

Next Step Prepare to Evaluate

∴

I b = \frac{5.7E-8 \cdot (85^{4})}{3.1416}

Next Step Evaluate

∴

I b = 0.942186763268463W/m²*sr

LAST Step Rounding Answer

∴

I b = 0.9422W/m²*sr
