No link pls. The link which you are providing me is of diff question. Pls do read my query correctly.
Ques
.
Two wavelengths of sodium light 590 nm and 596 nm are used in turn to study the diffraction at a single slit of size 4 mm. The distance between the slit and screen is 2 m. Calculate the separation between the positions of the first maximum of the diffraction pattern obtained in the two cases. (I want to learn how
do we assign the value of n here?- No link pls)
