Answer:
Explanation:
It is C. Environmental campaigns
how come?
f =1 10⁸ Hz
The speed of an electromagnetic wave is given by
c = Lam f
In our case, the wavelength is 3.0 m, so we can clear the frequency
f = c / Lam
f = 3 108/3.
False
Water contains ions that can conduct electricity and if touched it can cause harm (aka electrocution).
