Answer:
The frequency of the radio wave is
1

H
z
Explanation:
Let's use the this formula:
C
=
λ
×
v
C represents the speed of light, which has a value of approximately
3.00
×

8
m
s
λ
represents the wavelength and the units should be in meters.
v represents the frequency, which should have units of
H
z
or
s
−
1
. Hz is hertz or reciprocal seconds.
Now let's rearrange the equation to solve for v:
C
λ
