Well, they could be, but typically this would be called a WAN (wide area network), not a local area network.
In order to get the frequency of this light you have to d<span>ivide the speed of light by the wavelength.
The formula: </span>
![F = c / w](https://tex.z-dn.net/?f=F%20%3D%20c%20%2F%20w%20)
<span>
Set the values in the appropriate form:</span>
![740nm = 7.40e-9m](https://tex.z-dn.net/?f=740nm%20%3D%207.40e-9m%20)
Solution:
![3.00e8m/s : 7.40e-9m F = 6.38e16Hz](https://tex.z-dn.net/?f=%203.00e8m%2Fs%20%3A%207.40e-9m%20%0A%0A%0AF%20%3D%206.38e16Hz)
The answer: = 63.8PHz
i'm not sure sorry
I hope someone else can help you with this question
