Doppler effect the phenomenon, called the Doppler Effect, is a shift in the frequency and wavelength of waves, including sound and
light, resulting from relative motion between the source of the wave and the medium. If the source and receiver approach each other, the perceived frequency
will be higher. If they're separating, the perceived frequency will be lower |

Echoes
Echoes can be used to tell how far away an object is, how fast the object is
moving, and even its shape |

Modes of sound wave propagation modes of sound wave propagation. In air, sound travels by compression and rarefaction of air molecules in the direction
of travel. However, in solids, molecules can support vibrations in other directions, hence, a number of different types (modes) of sound waves are
possible |

Sound is a mechanical wave since a sound wave is a disturbance which is transported through a medium via the mechanism of particle interaction, a sound
wave is characterized as a mechanical wave |

Sound propagation
sound is a disturbance of the atmosphere that human beings can hear. Such disturbances are produced by practically everything that moves,
especially if it moves quickly or in a rapid and repetitive manner |
|
Sound Spectrum
A sound spectrum is a representation of a sound - usually a short sample of a
sound - in terms of the amount of vibration at each individual frequency. It is
usually presented as a graph of either power or pressure as a function of
frequency |
|
Sound wave interference explains what happens to the energy of sound waves when the waves interact, compare and contrast constructive interference and
destructive interference |
|
Sound wave propagation sound wave propagation. In air, sound travels by compression and rarefaction of air molecules in the direction of travel |
|
Sound waves
sound is a compression waveform that moves through air or other materials. Sound
waves are created by the vibration of some object and are detected by causing a
sensor to vibrate. Sound has the standard characteristics of any waveform |

Ultrasonic testing Ultrasonic Nondestructive Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic
inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more |
