Answer:
Explanation:
The electric field equation of a electromagnetic wave is given by:
(1)
- E(max) is the maximun value of E, it means the amplitude of the wave.
- k is the wave number
- ω is the angular frequency
We know that the wave length is λ = 700 nm and the peak electric field magnitude of 3.5 V/m, this value is correspond a E(max).
By definition:
And the relation between λ and f is:
The angular frequency equation is:
Therefore, the E equation, suing (1), will be:
(2)
For the magnetic field we have the next equation:
(3)
It is the same as E. Here we just need to find B(max).
We can use this equation:
Putting this in (3), finally we will have:
(4)

In an arithmetic progression, consecutive terms differ by the same value.
So, we have
which reflects the fact that the difference between P and 6 must be the same than the one between P and 14.
The equation solves to
And in fact, if you start with
every pair of consecutive terms differ by 4.
