What is the electromagnetic flux coming from the surface of a 2000K blackbody? (You must show your work for full credit

To determine the electromagnetic flux coming from the surface of a blackbody, you can use the Stefan-Boltzmann law. The Stefan-Boltzmann law states that the total electromagnetic flux emitted by a blackbody is proportional to the fourth power of its temperature.

The equation for the Stefan-Boltzmann law is:

F = σ * T^4

Where:
F = Electromagnetic flux (energy per unit area per unit time) in watts per square meter (W/m^2)
σ = Stefan-Boltzmann constant = 5.67 × 10^-8 W/(m^2·K^4)
T = Temperature of the blackbody in Kelvin (K)

In this case, the temperature of the blackbody is 2000K. We can now substitute the values into the formula and calculate the electromagnetic flux:

F = 5.67 × 10^-8 W/(m^2·K^4) * (2000K)^4

Simplifying the equation:

F = 5.67 × 10^-8 W/(m^2·K^4) * 16,000,000 K^4

F = 9.072 × 10^7 W/m^2

Therefore, the electromagnetic flux coming from the surface of a 2000K blackbody is approximately 9.072 × 10^7 watts per square meter (W/m^2).
