In an unstable atomic nuclei
Answer:
0.3376 mm
Explanation:
The computation of the spacing in mm between the slits is shown below:
As we know that

where,
= wavelength
L = distance from the scrren
= spanning distance
As there are 11 bright fingers seen so m would be
= 11 - 1
= 10
Now placing these values to the above formula
So, the spacing is

= 0.3376 mm
We simply applied the above formula.
