And for that matter, HOW would you do this? Through a mechanical wave pulse of immense intensity & impulse, we can create a standing wave that pulverises the building! Sound. This wave would travels through the metal, concrete and so on, much more dense than the air around it.

The "Dragon Eye" wave in the Qiantang River, China, is a tidal bore, a natural phenomenon where the incoming tide forms a wave that travels up the river, reversing its current

This is how a human finger interacts with a 60GHz electromagnetic wave! A mm wave radar can precisely track and capture the smallest kind of motion! Simulated in #openEMS and rendered in #blender3d !

Ever wonder how Mass IS Energy? Check out this visual of a light wave forming into a toroid (smoke ring) creating an electron.

A visualisation of different velocity factors in a PCB. Both simulations use the same excitation and port parameters. Only the permittivity is different, showing how the signal travels much faster in low Dk dielectrics. This simulation shows an embedded trace. A signal on an outer layer also travels faster because part of the EM field propagates through air, which has a Dk very close to 1

Here's a comparison of swimming pools on Earth, Mars, and the Moon. Splash Earth Mars > Moon Relative to Earth: the Wave height on Mars is about 1.6x, and travels at 0.6x the speed. The wave height on the Moon is about 2.5x, and travels at 0.4x the speed. The model is idealized of course, and these numbers are for the pool’s waves, but not the height of airborne splash droplets, just FYI.
