Understanding Electromagnetic Wave Propagation

In summary, propagating as a wave is not always the most intuitive explanation, but it is the most accurate one. While some phenomena can be explained using a particle-like view, others, like Young's interference experiment, require a wave-like explanation. And even in the case of bees, their flight pattern is actually more of a wave than a straight line.

Hello, why an electromagnetic signal propagate as wave? Wouldn't be more normal that electron travel in a beeline?

Thank you.

It would be more normal (at least for some meanings of what is 'normal'), but unfortunately it is not.

Propagating as a wave does not mean that for many purposes you can't use the bullet (bee) view. But in some phenomena you may observe (e.g. Young's interference experiment) light propagation could really be hard to explain in other view than wave.

By the way: bees also travels waving, rather along beeline. Every time bee flaps wings down - she moves body up. And a moment later, flapping wings up - moves body down. In the effect, her trajectory is pretty sinusoidal.

Thank you.

What exactly do you mean by an "electromagnetic signal?" To me it means (at first glance) "electromagnetic wave" such as a radio wave, which is not the same thing as a stream of electrons.
 

1. What is electromagnetic wave propagation?

Electromagnetic wave propagation is the process by which electromagnetic waves, which are a combination of electric and magnetic fields, travel through space. This phenomenon is responsible for the transmission of various forms of energy, including light, radio waves, and microwaves.

2. How do electromagnetic waves propagate?

Electromagnetic waves propagate through a vacuum or a medium by oscillating electric and magnetic fields. These fields are perpendicular to each other and to the direction of the wave's motion. The energy of the wave is transferred as these fields oscillate.

3. What factors affect electromagnetic wave propagation?

The main factors that affect electromagnetic wave propagation include the frequency and wavelength of the wave, the properties of the medium through which it is traveling, and any obstacles or barriers that it may encounter along its path.

4. How is the speed of electromagnetic waves determined?

The speed of electromagnetic waves is determined by the properties of the medium through which they are traveling. In a vacuum, the speed of light is approximately 3 x 10^8 meters per second. In other mediums, the speed may be slower due to interactions with particles in the medium.

5. How is electromagnetic wave propagation used in technology?

Electromagnetic wave propagation is used in a variety of technologies, including wireless communication, radar, and satellite systems. These technologies utilize the ability of electromagnetic waves to travel long distances and penetrate various materials, making them essential for modern communication and navigation.
