What type of wave is a sound wave? - Answers Sound waves are a type of longitudinal wave that travel through a medium by compressing and expanding the particles in the medium in the direction of the wave's motion
What kind of wave does sound travel at? - Answers A sound wave is a compression wave, which travels through the air in patterns of called "compressions" and "rarefactions", which are areas of higher than normal and lower than normal air pressure
An earthquake produces which kind of sound before the main shock wave . . . Earthquake is a movement of tremor of the earth's crust It originated naturally and below the surface An earthquake produces infrasound before the mainshock wave begins Infrasound is low-frequency sound less than 20hz It can travel hundreds of km through the earth's surface So by detecting this sound, we can predict an earthquake
Earthquake produces which kind of sound before the main shock wave . . . Earthquake produces infra-sound before the main shock wave Infrasound is a low-frequency sound It is sound that is lower in frequency than 20 Hz (hertz) or cycles per second, the normal limit of human hearing Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high The ear is the primary organ for
