Answer:
β 2 = 0.02575 mm
Step-by-step explanation:
given data
wavelength = 563 nm
separation distance between adjacent bright fringes = 0.0290 mm
wavelength = 500 nm
solution
we get here separation distance between adjacent bright fringes that is express as
β =
..................................1
here D is distance from plane of slit to screen
and d is slit sepation that is constant
so
β 2 =
β 2 = 0.02575 mm
