The simplest form of a traveling electromagnetic wave is a plane wave. For a wave traveling in the x direction whose electric fi
e-lub [12.9K]

Answer:

please the answer below

Explanation:

A general electromagnetic plane wave, traveling in the x direction, can be expressed in the form:

\vec{E}=E_0e^{-i(k\cdot x-\omega t)}\hat{j}\\\\\vec{B}=B_0e^{-i(k\cdot x-\omega t)}\hat{k}\\\\    (1)

1.

a. amplitudes

from (1) we can observe that E_0 and B_0 are the amplitudes.

2. frequency

3.

By replacing  (1) we obtain:

\vec{E}=E_0e^{-i(k(0)-\omega t)}\hat{j}=E_0[cos\omega t+sin\omega t]\hat{j}

4.

the wave respond to the followinf physical variables: amplitude, frequency, time and position, as we can see in (1).

hope this helps!!

If the magnitude of the magnetic force on a proton is F when it is moving at 14.0 o with respect to the field, what is the magni
sergeinik [125]

Answer:

The magnitude of the magnetic force at 32.5⁰ to the field, is 2.22 F

Explanation:

Given;

magnitude of the magnetic force is F at 14.0⁰ with respect to the field.

To determine the magnitude of the magnetic force at 32.5⁰ to the field, we apply the following formula and solve with proportion;

f*Sin(14.0⁰) = F

f*Sin(32.5⁰) = ?

= \frac{f*Sin(32.5^o)}{f*Sin(14.0^o)}.F\\\\ =2.22 \ F

Therefore, the magnitude of the magnetic force at 32.5⁰ to the field, is 2.22 F
