FAQ
Frequently Asked Questions
In air, yes, sound is a compression wave. However, 'compression wave' is a broader physics term applicable to any medium (e.g., rock, water).
A shock wave is an extreme, discontinuous compression wave characterised by an abrupt, nearly instantaneous change in pressure, temperature, and density.
P-wave stands for 'Primary wave' or 'Pressure wave' because it is the first to arrive from an earthquake due to its higher speed.
Not directly, but its effects can be visualised with specialised equipment (e.g., Schlieren photography for air, seismographs for ground movement).
A wave in which the medium is compressed in the same direction as the wave's travel.
Compression wave is usually technical/scientific in register.
