Answer:
<h3>(A) The width
m</h3><h3>(B) The new width is
m</h3>
Explanation:
Given :
Focal length 
Maximum aperture 
Wavelength 
m
(A)
From rayleigh criterion,
rad
From angle formula,
Where 
12 m ( given in example )
m
m
(B)
We know that 
is proportional to the 
and inversely proportional to the 
so we write the new width, here is 5.5 times larger than above case
m
