define propagation of sound
Answers
Answer:
The Propagation of sound. Sound is a sequence of waves of pressure which propagates through compressible media such as air or water. (Sound can propagate through solids as well, but there are additional modes of propagation). During their propagation, waves can be reflected, refracted, or attentuated by the medium.
Answer:
Explanation:
Sound need a material medium like air,water,steel for its propagation.it cannot pass through a vaccum. Sound waves are characterised by the motion of particles of a medium and are called mechanical waves.
A wave is a disturbance that moves through the medium when the particles of the medium set neighbouring particles into motion.
The disturbance created by a source of sound in a medium travels through the medium and not the particles of the medium.
