Engineers created the loudest sound possible underwater

The strength of sound on Earth has an upper limit - in air it is 194 dB, under water - 270 dB. The point is that when

When these marks are reached, the medium in which sound waves propagate begins to collapse and the sound cannot become louder.

This is exactly what happened when researchersThey used an X-ray laser to hit the water. As the water evaporated, it created a shock wave, which then split into zones of high and low pressure.

During the experiment, researchers found: as soon as the sound intensity exceeded a certain threshold, the water disintegrated and turned into small steam-filled bubbles, which immediately collapsed in a process called cavitation.

Previously, researchers from Harvard Schooltechnical and applied sciences for the first time used a semiconductor laser for transmitting and receiving radio signals. In the future, a hybrid electronic photonic device will create ultra-high-speed Wi-Fi.
