The Total solution for NCERT class 6-12
In double-slit experiment usinglight of wavelength 600 nm, the angular width of a fringe formed on a distantscreen is 0.1º. What is the spacing between the two slits?
Wavelength of light used, λ = 6000 nm = 600 × 10−9 m
Angular width of a fringe isrelated to slit spacing (d) as:
Therefore, the spacing between the slits is
