Answer:
They can be seen from a distance of 4.372 kilometers.
Explanation:
Using the Reyligh creterion for diffraction through a circular aperture we have
where symbol's have their usual meaning
thus applying values we get
![D=\frac{dx}{1.22\lambda }](https://tex.z-dn.net/?f=D%3D%5Cfrac%7Bdx%7D%7B1.22%5Clambda%20%7D)
![\therefore D=\frac{0.633\times 4.61\times 10^{-3}}{1.22\times 547\times 10^{-9}}\\\\D=4372.77m\\=4.372km](https://tex.z-dn.net/?f=%5Ctherefore%20D%3D%5Cfrac%7B0.633%5Ctimes%204.61%5Ctimes%2010%5E%7B-3%7D%7D%7B1.22%5Ctimes%20547%5Ctimes%2010%5E%7B-9%7D%7D%5C%5C%5C%5CD%3D4372.77m%5C%5C%3D4.372km)
