Answer:
a
The number of fringe is z = 3 fringes
b
The ratio is
Explanation:
a
From the question we are told that
The wavelength is
The distance between the slit is
The width of the slit is
let z be the number of fringes that appear between the first diffraction-envelope minima to either side of the central maximum in a double-slit pattern is and this mathematically represented as
Substituting values
z = 3 fringes
b
From the question we are told that the order of the bright fringe is n = 3
Generally the intensity of a pattern is mathematically represented as
Where is the intensity of the central fringe
And Generally
