College Physics: Reasoning and Relationships
A sound wave in air has a frequency of 220 Hz. What is its wave- length? The
distance along a sound wave between a point of condensa- tion and the nearest
rarefaction is 0.45 m. What is the wavelength of this sound wave? 3. Consider a ...

Multi-Track Recording for Musicians
There are four other important concepts to learn about components of sound
waves : • The amplitude of a sound wave determines how loud it sounds to us. •
The decibel is the measure of amplitude. • Sound waves have different phase
cycles.

Diagnostic Ultrasound: Physics and Equipment
As explained earlier, a sound wave passing through a medium causes the
particles of the medium to oscillate back and forth along the direction of
propagation (i.e. longitudinally). The maximum distance moved by a particle from
its normal rest ...

Physics of
Sound in the Sea
It can be shown theoretically that whenever a sound wave travels through a
portion of a fluid where the density or sound velocity varies with position, some
energy is radiated in directions differing from the original direction of the wave.

Science Australia: Book 3
When a sound wave in the air meets a hard surface, most of the sound is
reflected. This is how an echo is made. Light is also reflected from a surface. The
angle at which light reflects from the surface is always the same as the angle at
which it ...
