Higher Order Diffraction: Why Do Colors Appear Different and Overlap?

AI Thread Summary
In higher order diffraction, colors are more spread out compared to lower orders, yet the sequence remains consistent as ROYGBIV. Negative orders result in a reversal of color arrangement. Overlapping of higher order colors can create confusion when observing the complete diffraction pattern. Understanding these differences is crucial for interpreting diffraction results accurately. The unique behavior of colors in higher order diffraction highlights the complexity of light interactions.

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.

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
