Difference between the spectra obtained through prism and grating?

Click For Summary

Discussion Overview

The discussion centers on the differences between the spectra produced by prisms and diffraction gratings, focusing on their resolution and free spectral range. The scope includes conceptual understanding and technical comparison of these optical devices.

Discussion Character

  • Technical explanation

Main Points Raised

  • Some participants note that the resolution of a diffraction grating is much higher than that of a prism.
  • Others point out that the free spectral range of a prism is much higher than that of a diffraction grating.

Areas of Agreement / Disagreement

Participants present differing views on the characteristics of prisms and gratings, indicating that multiple competing perspectives remain regarding their comparative advantages.

Contextual Notes

The discussion does not resolve the implications of resolution and free spectral range in practical applications or specific contexts.

i want a clear picture...
 


The resolution of a diffraction grating is much higher than a prism.

Conversely the free spectral range of a prism is much higher than a diffraction grating.

Nice comparison, Claude, for my own knowledge. Thanks.
