Refractive index bacteria

WebBacteria have nearly the same refractive index as water, therefore, when they are observed under a microscope they are opaque or nearly invisible to the naked eye. Different types of staining methods are used to make the cells and their internal structures more visible under the light microscope. 2 Slide 3 Webrefractive index: the ratio of the speed of light in air or vacuum to that in another medium. Phase-contrast microscopy is a method of manipulating light paths through the use of strategically placed rings in order to illuminate transparent objects.
