Question

Sodium light has two wavelengths as the path difference

Answer 1

Answer:

Sodium light has two wavelengths 589 nm and 589.6nm, as the path difference increases when is the visibility of fringes a minimum? ... The fringe pattern will consist of a superimposed pattern of fringes from the 589.6 nm line and the 589.0 nm line, with the fringes from the 589.0 nm ...
