What evidence is there that radiowaves have the character of a wave?

In experimental configuration, radio signals exhibit refraction, reflection, dispersion,
constructive and destructive interference ... all easily explained with reference to waves.
Also, a lot of wave-math in the 1860s and 70s accurately predicted how radio would behave
before the first signals were ever generated.
Of course, none of that proves anything, and the conjecture is still "just a theory".
All of those accurate predictions and consistent experimental results sure seem to
support the hypothesis that radio signals travel in the form of waves, but if you offer
a different explanation tomorrow that more accurately describes how they behave, then
the wave theory will be thrown out, and your explanation will become the preferred
hypothesis.
Nothing can 'prove' the theory in a thousand years, but a new explanation can disprove it
in a month. That's how science works.

What is an example of an electromagnetic wave?
x-rays, radiowaves, microwaves
What can you use radiowaves for?
Radiowaves can be used for communication. Radio stations use radiowaves to broadcast their content to radios.
What happens when a metal TV aerial absorbs a radio wave?
Yes, since metal plate or any other types of metals have free electrons they can absorb radiowaves since radiowaves travel through free electrons.
How does the wavelength of a wave change when the frequency changes?
Usually with electromagnetic waves, the frequency and energy is opposite to the wavelength. An EM wave such as radiowaves have huge wavelengths, slow frequencies and small amounts of energy. An EM wave such as X-rays have tiny wavelengths, fast frequencies and large amounts of energy.
What is visible evidence of energy passing through the water?
A wave is visible evidence.
What is an example of an electromagnetic wave?
x-rays, radiowaves, microwaves
Does sound travel in a wave?
yes sound travels in a wave known as the soundwave like many others(radiowaves,microwaves,and heatwaves)
Are microwaves higher in frequency than short wave radio?
Yes but has shorter wavelength than radiowaves.
What has to happen to sound wave before they can be transmitted by radiowaves?
The sound signal must firstly be changed into an electrical signal.
What can you use radiowaves for?
Radiowaves can be used for communication. Radio stations use radiowaves to broadcast their content to radios.
When was Radiowaves created?
Radiowaves was created on 1997-09-16.
What happens when a metal TV aerial absorbs a radio wave?
Yes, since metal plate or any other types of metals have free electrons they can absorb radiowaves since radiowaves travel through free electrons.
What is the name of the wave that can travel through vacuum and how does it related to television?
Electromagnetic waves can travel in a vacuum. Radiowaves, which are used in television signals, are one part of the electromagnetic spectrum.
What type of wave only travels through solids and what does this give evidence of?
It's an 'S wave'. Im not entirely sure what it gives evidence of but i believe that it is a seismic wave.
How does the wavelength of a wave change when the frequency changes?
Usually with electromagnetic waves, the frequency and energy is opposite to the wavelength. An EM wave such as radiowaves have huge wavelengths, slow frequencies and small amounts of energy. An EM wave such as X-rays have tiny wavelengths, fast frequencies and large amounts of energy.
What evidence is there that the radio waves has the character of a wave?
We make that assumption from scanty, flimsy evidence. The only indication we have is that radio waves exhibit all the properties of reflection, refraction, diffraction, dispersion, polarization, and interference that are characteristic of waves, and that they all closely match the mathematics of wave motion. Other than that, there's nothing to go on.
When can a witness bring in character evidence of his her good character?
A witness can bring in character evidence of their good character when their character is relevant to the case, such as when their credibility is being challenged. This type of evidence can be used to show the witness's reputation for honesty or truthfulness.
