Calculating energy from flux and max wavelength

Click For Summary
SUMMARY

The discussion focuses on calculating the total energy emitted by a blackbody emitter using its flux and peak wavelength. To determine the temperature, users should apply Wien's Displacement Law, represented by the equation λmax T = 2897.8 µm-K. Subsequently, the total power can be calculated using the Stefan-Boltzmann Law, expressed as E = σ T4, where σ is the Stefan-Boltzmann constant.

PREREQUISITES
  • Understanding of Wien's Displacement Law
  • Familiarity with the Stefan-Boltzmann Law
  • Knowledge of blackbody radiation concepts
  • Basic proficiency in physics and thermodynamics
NEXT STEPS
  • Research the application of Wien's Displacement Law in different contexts
  • Study the Stefan-Boltzmann Law and its implications in thermal radiation
  • Explore blackbody radiation and its significance in astrophysics
  • Learn about the calculation of energy flux in various materials
USEFUL FOR

Physicists, engineers, and students studying thermodynamics or astrophysics who are interested in understanding blackbody radiation and energy calculations.

hey I am calculating energy of a blackbody emitter, and i have the flux (energy per unit area) and the peak wavelength emitted. how do i calculate total energy?

Since you have your peak wavelength, use Wein's Displacement Law to find the temperature of your black body emitter:

\lambda_{max} T = 2897.8 um-K

Then apply Stepan-Boltzmann Law to find total power:

E = \sigma T^{4}.
