Resonance

[rupol2000]

Such an experience is described. When they hit one tuning fork and then muffle it, the second tuning fork sounds.

However, resonance is defined as the coincidence of vibrations.
The second tuning fork starts oscillating from zero, it swings with the help of the waves of the first.

This means that the correct definition of resonance should be as follows:

Resonance is the ability to create vibrations in another body through the air flow of waves.
Оr simply transmitting vibrations through sound

Right?

Does that apply to the problem of resonance in bridges?

I think yes.
Bridges can be destroyed even by normal wind

Not really. For example - 1). electrically applying a low audio frequency signal to an electromagnet causes the "voice" coil of a simple woofer speaker to resonate in response. No air required. 2). the mechanical woofer action then alternately compresses and rarifies the air medium which longitudinally transfers the signal in wave fashion to one's ear. 3). The ear then reverses the speaker process, converting the mechanical "sound" wave back into an electrical signal which the brain then processes as a "sound."

Resonance is a factor at each stage, both aiding and impeding forward transfer. The desired signal energy moves through well where the output and input impedances best "match" over the range of frequencies applied. Google says:

resonance, in physics, relatively large selective response of an object or a system that vibrates in step or phase, with an externally applied oscillatory force. Resonance was first investigated in acoustical systems such as musical instruments and the human voice.

But in no way is it limited to sound or air. Light energy resonates as well and traverses space by similarly compressing and rarefying the Aether medium between transmitters and receivers.
