Refractive index bacteria
WebIn optics the refractive index or index o refraction n o a substance (optical medium) is a dimensionless nummer that describes hou licht, or ony ither radiation, propagates throu that medium.It is defined as =, whaur c is the speed o licht in vacuum an v is the speed o licht in the substance.

WebThis is related to the opening angle of the lens and its refractive index. The resolution of a microscope is defined as the minimum separation needed between two objects under examination in order for the microscope to discern them as separate objects. This minimum distance is labelled δ. WebThe bacterial cells will appear just as bright as the surrounding medium and there is no color contrast. Phase contrast optics provides a solution. Phase contrast optics convert the differences in optical density (i.e. the refractive index) of the bacterial cells into different shades of brightness.
