SUMMARY

The discussion centers on identifying a general term for curves resembling blackbody radiation curves, specifically the Planck curve. Participants question whether the observed curve is a true Planckian distribution or simply a bell curve or a 1/x^4 function. The original poster expresses uncertainty about the terminology, indicating that the curve's characteristics, such as asymmetry and a long tail, lead to confusion regarding its classification. Ultimately, no definitive general name for such curves is established in the conversation.

PREREQUISITES
  • Understanding of blackbody radiation and its characteristics
  • Familiarity with Planck's law and Planckian distributions
  • Knowledge of curve types, including bell curves and power-law distributions
  • Basic plotting skills using data visualization tools
NEXT STEPS
  • Research the properties of Planckian distributions in detail
  • Explore the mathematical definitions of bell curves and power-law distributions
  • Learn about data visualization techniques for plotting complex curves
  • Investigate the applications of blackbody radiation curves in physics and engineering
USEFUL FOR

Physicists, data analysts, and anyone interested in the mathematical modeling of curves related to thermal radiation and data visualization techniques.

I was plotting some data and got a curve that was instantly recognizable as a blackbody radiation curve. The data has nothing to do with blackbody radiation though, and I was wondering if there was a more general name for this type of curve?

To be clear, I mean a curve like these:

Planck curve, perhaps?

Are you sure it's a true Planckian distribution, and not just a bell curve or a 1/x^4?

I don't know what a Planckian distribution is, but it has nothing to do with Planck's constant. Just happened to look similar to blackbody radiation curves, with the non symmetry and long tail. Just kind of figured there was a more general name for that kind of curve, but guess not. Thanks for your help.

Here's the plot, which I guess I should have attached in the first place:
