A Young's slits experiment is carried out using monochromatic light of wavelength 506 nm.The slit separation is 4.42x10-4 m, and the screen is placed 1.00 m from the slits.
Calculate the spacing between adjacent bright fringes, in m, to 3s.f.
Condition for constructive interference in Young's double slit experiment is
Where,
is distance of nth bright fringe from central bright fringe.
is the distance between the slits and the screen.
is distance between the two slits.
is the wavelength of light used.
The spacing between the adjacent bright fringes can be calculated by
So the spacing between two adjacent bright fringes is 1.145 x 10-3 m.
