SUMMARY

The discussion focuses on the differences in color arrangement observed in higher order diffraction patterns compared to the first and second orders. Participants noted that while the sequence of colors remains consistent (ROYGBIV), higher orders exhibit greater dispersion and potential overlap, particularly in negative orders where colors appear reversed. This phenomenon can lead to confusion when analyzing the complete diffraction pattern.

PREREQUISITES
  • Understanding of diffraction principles

Hi everybody ,Why arrangement of colors in higher order of diffraction is different from order 1 , 2 ?
Thanks

The colors are spread out more, but the order of the colors should be the same (ROYGBIV). But if you go to a negative order, the colors are reversed.
 
Also, the higher orders may overlap, which can confuse you if you're looking at the entire pattern.
