Sound waves cannot travel space since it is a vacuum and there is no medium to transmit these mechanical waves. Ocean waves are mechanical waves, too. They're also not just wiggly water!

For the first time, researchers were able to transmit, or "tunnel," sound waves across extremely small distances between two crystals in a vacuum. For the first time, scientists have shown that ...

In such materials, vibrations (sound waves) produce an electrical response, as well, and since an electric field can exist in vacuum, it can transmit the sound waves across. The requirement is ...

This innovative device uses a tri-layer metallic metasurface to achieve independent modulation of the phase and polarization state of transmitted THz waves. The work designs two efficient vector ...

The dielectric constant influences how electromagnetic waves interact with a material. It affects the amount of radiation ...

Researchers at ETH Zurich have created a T-shirt that can measure breathing and gloves that can translate hand movements into commands for a computer. Led by Professor Daniel Ahmed, researchers ...

The digitised sound will be transmitted to the large 35-metre satellite dish at ESA's Cebreros ground station in Spain.
