Explanation:
Answer:
λ = 1.2 x 10⁻⁶ m
Explanation:
Given that,
slit separation, d = 0.050 mm
= 5 x 10⁻⁵ m
Distance between the fringes, D = 5.00 m
distance between the fringes, x = 12.0 cm
= 0.12 m
wavelength of the light = ?
the separation between the fringe is given by
where as n = 1
λ = 1.2 x 10⁻⁶ m
