s=e h This is the energy flow density vector, there is also a h=(n h) relationship between the electric field and the magnetic field, this formula illustrates the propagation relationship between the electric field and the magnetic field, the transverse wave and the transverse magnetic wave are generated by the superposition between the electromagnetic field, for example, in the reflection process of the electromagnetic wave, the superposition of the incident wave and the reflected wave, when the electromagnetic wave is incident with perpendicular polarization, the transverse electric wave appears, and the transverse magnetic wave occurs when it is incident with parallel polarization, and the theoretical derivation of this phenomenon first assumes that the incident wave propagation wave vector, Using Fresnel's formula and h=(n h) to find the reflected wave vector for superposition, the results show that when the vertical polarization occurs, the electric field has only a transverse component, and the magnetic field has both transverse and longitudinal components, which is the transverse wave, and when the parallel polarization is incidence, the magnetic field has only a transverse component, and the electric field has both transverse and longitudinal components, which is the transverse magnetic wave, that is, the wave is a non-uniform plane electromagnetic wave. It can be observed that the basic relationship between the electric field and the magnetic field h=(n h) is used in the derivation of these theories, so the results obtained are of course satisfied with s=e h

To be honest, I don't see what your equation is, have you ever heard of a ** circuit? **There is electromagnetism in the circuit**.
There is an elective 3-4 in the high school book, which introduces electromagnetism in great detail.
The changing magnetic field produces an electric field.
Our electromagnetic waves are periodically varying magnetic fields that produce periodically varying electric fields.
A periodically varying electric field produces a periodically varying magnetic field.
The direction of change of the magnetic field and the electric field is perpendicular to each other
For visual representation, put them into a three-dimensional coordinate system.
I can't go on.
You go and see 3-4 handfuls!

They are all transverse waves, there are electric field fluctuations, there are magnetic field fluctuations, and the direction of the magnetic field is also perpendicular to the direction of propagation.

Electromagnetic waves are not mechanical waves, and the propagation of electromagnetic waves is an alternating change between the electric field and the magnetic field, which does not depend on the vibration of particles in the propagation medium, and there is no difference in the vertical and horizontal directions.

Electromagnetic waves are – transverse waves – not longitudinal waves.

A wave is the propagation of vibrations in space. For example, sound waves propagating in the air, water waves propagating on the water surface and ** waves propagating in the earth's crust, etc., are all broadcast in the elastic medium by the vibration emitted by the vibration source, and these waves are collectively called mechanical waves. Light waves, thermal radiation, microwaves, radio waves, etc. are all electromagnetic oscillations emitted by the source of vibration propagation in space, these waves are called electromagnetic waves.
Electromagnetic waves are electric and magnetic fields that oscillate in phase and are perpendicular to each other in the form of waves in space, and their propagation direction is perpendicular to the plane composed of electric and magnetic fields, so they are transverse waves.
Why are electromagnetic waves transverse waves.
The periodic change of the electric field and the magnetic field excite each other, and the electromagnetic field formed is itself a vibration, so to speak, the vibration of the electric field (the change of field strength e) causes the magnetic field, and the vibration of the magnetic field (the change of the magnetic induction intensity b) excites the electric field, they are like branches growing on the trunk of a tree, and the direction of vibration is perpendicular to the direction of propagation of the wave, so the electromagnetic wave is a transverse wave.
Why are electromagnetic waves transverse waves.
The direction of the speed of the electromagnetic wave, the direction of the base magnetic induction intensity b, and the direction of the electric field intensity e are perpendicular to each other, then the square of the wave is perpendicular to the magnetic induction intensity and the electric field intensity, then the Zen mega electromagnetic wave is a transverse wave.
Why are electromagnetic waves classified as transverse waves.
You have a point, and here it is controversial. Different references have different definitions of things. For example, if a pool of water waves is blown, is the water wave transverse or longitudinal?
So in the same way, the electromagnetic wave is a transverse wave, but from a microscopic point of view, the essence is caused by the density of internal photons, that is, the longitudinal wave.
Are electromagnetic waves transverse waves and why are they transverse waves? Thank you..
The landlord only needs to understand the concept of transverse waves.
1。The direction of vibration and propagation of transverse waves is perpendicular ingots, and electromagnetic waves are such waves.
2。The waves generated by spring simulations are longitudinal waves.

Electromagnetic waves are formed by the propagation of a periodically varying electric field and a periodically varying magnetic field in the air. The periodically changing electric field can excite the periodically changing magnetic field, and the periodically changing magnetic field can also excite the periodically varying electric field, they excite each other, propagate in the air, do not need a medium, so they can propagate in the air, and can also propagate in a vacuum, while the medium is needed when the mechanical wave propagates, so the air cannot propagate the transverse wave in the mechanical wave, but may propagate electromagnetic waves.

Electromagnetic waves are transverse waves, which refer to the magnetic field, electric field and direction of propagation of electromagnetic waves perpendicular to each other. Perpendicular to the direction of propagation is not the vibration of the particle in the mechanical wave, but the electric and magnetic fields!! Of course, it can be propagated in a vacuum.

Air cannot propagate transverse mechanical waves, and electromagnetic waves are not mechanical waves. As long as it's transparent, it's fine.
Electromagnetic waves have mass, of course, if they are moving. >>>More
Electromagnetic waves are a form of motion in an electromagnetic field. Electricity and magnetism can be said to be two sides of the same coin, a changing electric field will produce a magnetic field (i.e., an electric current will produce a magnetic field), and a changing magnetic field will produce an electric field. The changing electric field and the changing magnetic field constitute an inseparable unified field, which is the electromagnetic field, and the propagation of the changing electromagnetic field in space forms electromagnetic waves, and the changes in electromagnetism are like water waves generated by the breeze on the water surface, so they are called electromagnetic waves, also known as radio waves. >>>More
This problem is still unsolvable in today's scientific community, and there are countless hypotheses, which you can basically find at once.
First, the reason for the crash is that the machine cannot be turned on. >>>More
