So the waves pile up against each other as they are created. These "piled up" waves are called shock waves. The greatest shock waves are at the tip and tail of the plane. This NASA photograph ...

Shock waves can be artificially generated by discharge of a high-voltage spark under water. Cardiac SW therapy (CSWT) is performed using a SW generator system designed to address the clinical ...

This results in a shock wave of pressurized air molecules, which form a cone-shaped sheath around and behind the plane. This cone-shaped shock wave wouldn't be a problem if it lost its strength as ...
