Answer:

Check the explanation

Explanation:

It is basically known that the change in complex compositions of metal play a vital role in the conduction of molecular materials, which display atypical magnetic properties and conducting which also finds applicability in material chemistry, supramolecular and biochemistry, The electrochemical conduct of the nickel Ni(II) complexes was investigated in DMSO by cyclic voltammetry (CV), rotating coulometry and disc electrode (RDE).

The solution to the question above can be seen in the attached image below

Hertz is units for frequency. (waves per second)
wavelength = speed/frequency

if you're given the speed use that to calculate, if not then you can probably assume it's a wave of light and use the speed of light (3x10^8 m/s) to calculate.

wavelength = (3x10^8)/(1.28x10^17)
= 0.000000002 m
= 2.34 nm
