Explanation:
From the question we are told
The frequency of the electromagnetic wave is
The peak value of the electric field is
Generally the intensity of this wave is mathematically represented as
Where c is the speed of light with value
is the permittivity of free space with value
Substituting values into equation for intensity
Converting to we divide by 10,000
And the answer is False.
