Explanation:
frequency= velocity/ wavelength
= 340/1.36
=250
K= [Ar] 4s^1
Pb= [Xe] 6s^2 5d^10 6p^2
Sc= [Ar] 4s^2 3d^1
Ra= [Rn] 7s^2
O= [He] 2s^2 2p^4
Ag= [Kr] 5s^2 4d^9
Ru= [Kr] 5s^1
Ce= [Xe] 6s^2 5d^1 4f^1
I= [Kr] 5s^2 4d^10 5p^5
F= [He] 2s^2 2p^5
1ft=.3048meter
So if we have 2063ft and want it in meters we just do a simple unit conversion.
(2063ft)(.3048meters/1ft)=628.8meters. Here ft cancel out and leave us with meter units.
Any questions please feel free to ask. Thank you.
