Answers

In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water particles.

Sound waves transfer energy by causing successive compressions and rarefactions in the particles of the medium without transporting the medium particles themselves.

Explanation:

Sound in solids can also manifest as transverse waves, causing crests and troughs in the propagation medium. Waves can be characterized by two basic parameters: amplitude and frequency. Focusing on a single point vibrating in a medium excited by a sound wave, amplitude is the maximum distance traveled by the vibrating point relative to its rest position. Taking a snapshot of a propagating sound wave at any instance shows consecutive compressions and rarefactions, regions in which the medium material is compressed together and spread widely apart, respectively. The distance between the centers of two successive compressions or rarefactions is the wavelength of the wave. The frequency is the inverse of the wavelength, so the larger the frequency, the smaller the wavelength. Having a higher frequency makes the wave have a larger number of more closely-grouped compressions and rarefactions as it propagates. As the amplitude and frequency of the wave increase, the energy transferred by the propagation of the wave also increases. Extremely short but low-amplitude ultrasonic waves can be used to heat polymer materials and weld them together.

Answer from: Quest

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
