Can light travels without electromagnetic field ?
Thanks

However, if the front and back sides of the surface, and the interior of the holes are metallic, then the impinging light can create plasmons, a quantum quasi-particle, then these plasmons can propagate through the holes, and when they reach the back side of the material they act as little antennas which regenerate the light that was incident on the other side of the holes.
Plasmons have both electric and magnetic fields associated with them, so perhaps this violates rule two.
No, light is an electromagnetic wave and therefore cannot exist without an accompanying electromagnetic field. The electric and magnetic fields are intertwined and work together to propagate the light wave through space.
The electromagnetic field is crucial for light to travel because it carries the energy and information of the light wave. It also determines the direction and speed of the light wave.
No, even in a vacuum, light cannot travel without an accompanying electromagnetic field. In fact, a vacuum is defined as a space devoid of matter but still containing an electromagnetic field.
When an electrically charged particle, such as an electron, is accelerated, it creates a disturbance in the electromagnetic field, which then propagates as a light wave. In other words, the electromagnetic field interacts with matter to produce light.
Yes, light can travel through a vacuum, which is essentially a space without a medium. This is because the electromagnetic field can propagate through empty space without the need for a physical medium.
