Answer to Question #117186 in Optics for Tanya

Question

In Wallostons air film experiment, what will happen if we will use the mercury as a source of light

Answer 1

We know that the mercury vapor light source gives light in the different-different spectrum, and the invisible spectrum is in the form of ultra violet radiations. Hence mercury vapor light is a chromatically light source. The resulting light is visible as close to the white light which is the combination of three primary colors.
