Solar spectral intensity per wavelength - frequency

Click For Summary

Discussion Overview

The discussion centers on the differences between solar spectral intensity when represented per wavelength versus per frequency. Participants explore the implications of these representations, particularly in relation to the shape of the intensity curves and the mathematical relationship between frequency and wavelength.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • Some participants suggest that the difference arises from the inverse proportionality between frequency and wavelength.
  • One participant notes that the shape of the intensity curve varies depending on whether it is plotted against frequency or wavelength, indicating a non-linear relationship.
  • A participant references an external resource that may provide further insights into the topic.

Areas of Agreement / Disagreement

Participants generally agree on the inverse relationship between frequency and wavelength but do not reach a consensus on the implications for the shape of the intensity curves.

Contextual Notes

The discussion does not resolve the specific reasons for the differences in curve shapes, and assumptions regarding the mathematical treatment of spectral intensity are not fully explored.

Why is solar spectral intensity per wavelength different than solar spectral intensity per frequency?

If I have understood you question correctly
... ( it didn't have much supporting info) ...
I would suggest because frequency and wavelength are inversely proportional...

increase freq. decrease wavelength and visa versa

If that isn't what you are looking for, then make your Q a bit easier to understand

Why the shape of the curve is different when the intensity is plotted in a graph against frequency and against wavelength? That is your question?

Shortly, because the relationship between frequency and wavelength is non-linear, indeed they are inversely proportional. You might read this insight:
