The <u>average</u> acceleration for an object undergoing this change in velocity is
(12.5 m/s - 8.3 m/s) / (1.24 s) = (4.2 m/s) / (1.24 s) ≈ 3.4 m/s²
Answer:
3 order dark fringe
Explanation:
y = Distance from central bright fringe = 204 mm
λ = Wavelength = 400 nm
L = Distance between screen and source = 1 m
d = Slit distance = 6 μm


Order of fringe is 3
So, it is a Dark order fringe
