Answer:
The wavelength of the given electromagnetic radiation is 3.25 m.
Step-by-step explanation:
We know that,
Frequency (f) = c / λ;
where,
c - speed of light =

λ - wavelength of the radiation.
Given,
f =
,
From the above formula,
λ =

λ =

λ = 3.25m;
Therefore,
Wavelength of the given radiation = 3.25 m
