If the direction of the electric field intensity vector of an electromagnetic wave changes with time, the trajectory traced by it is a circle, what is the wave called?

Transverse waves, because the electric field trajectory of the electromagnetic field forms a circle, is a plane. Even if the direction of the plane is not directly compared with the emission direction of transverse waves and longitudinal waves, we can also know that any direction of the plane is not the transmission direction, only the vertical direction of the plane The direction can be the direction of transmission

The direction of the magnetic field is the same as the direction of the electric field

Electromagnetic waves are typical chain cross transverse waves

It can be seen as a chain and an electric field chain loop Connect a vertical magnetic field link, then connect a vertical electric field link, and continue the wireless link. Any link is perpendicular to the extending direction of the chain, and the three of them are perpendicular to each other

The opposite direction of the extension is actually the electric field. Magnetization, the distance direction formed during the process of magnetization and electricity
