Using the appropriate approximations:
dx/L = mλ
d = slit separation
x = fringe spacing
L = distance between slits and screen
m = some integer, used to determine the distance from the central bright fringe to another bright fringe
We don't really need a value for m because we're calculating the distance between any pair of consecutive fringes. Let's just set m = 1
Given values:
d = 1.0mm
L = 2.0m
λ = 480nm
Substitute the terms in the equation with our given values and solve for x:
1.0*10⁻³*x/2 = 480*10⁻9
<h3>x = 0.96mm</h3>
Answer:

Answer:
Current in the battery will be 11.7 A
Explanation:
We have given that the there is parallel circuit with three different branches.
Current in each branch is
,
,
We have to find the current I in the battery
It is known that in parallel circuit current is sum of current in each branches
So current in the battery will be equal to


Therefore current in the battery will be 11.7 A
