refractive index and interference
Posted: Mon Oct 22, 2012 6:00 pm
Hi all,
For the savvy microscope"rs" in this forum I have a simple question that had asked me one student:
This is the text of his question. Any help will be appreciated, thx
0.6 wavelength vs. 0.4 wavelength
In a phase contrast image, would an organelle that causes the wave to be 0.4 wavelengths ahead of the surround and 0.6 wavelengths ahead appear the same color. They are both 0.1 wavelength away from maximum destructive interference (0.5 wavelengths and black) and thus I would imagine they would both appear the same shade of grey.
If this is the case, how can you tell if grey objects have a refractive index above or below black objects?
