Answer:
d = 1.30 mm
Explanation:
given,
wavelength of the light source (λ)= 502 nm
slits is separated (d) = ?
distance to form interference pattern(D) = 1.35 m
20 th fringe
y = 10.4 mm = 0.0104 m
now,separation between to slits
where y is the fringe width
d = 1.30 mm
separation between to slits is equal to d = 1.30 mm
