It’s the frequency of a sound wave. A sound wave has this form.

1 PT Pitch

Mechanical waves such as sound waves travel fastest through this

2 PT Solids (the particles are closest together).

A sound wave is this type and form of wave.

3 PT Mechanical and longitudinal (or compressional)

It’s another name for the energy of a wave; related to the amplitude

4 PT Intensity

It’s the spread-apart portion of a sound wave

5 PT rarefaction

Loudness is measured in these units

1 PT Decibels (dB)

This wave phenomenon is caused by a shift in frequency due to the motion of the source of a wave relative to the observer.

2 PT The Doppler Effect

It’s the direction a galaxy is moving when the galaxy is perceived to be red shifted.

3 PT Away from the observer

Ships use this technology with sound waves to locate submarines under water.

4 PT SONAR

The character of this determines the speed of any wave.

5 PT The medium through which the wave travels

The unit for frequency (and pitch)

1 PT Hertz (Hz)

It’s the type of wave shown below

2 PT transverse

It’s the speed of a sound wave that has a frequency of 33.3 Hz and a wavelength of 10 m.

3 PT 333 m/s

It’s the type of relationship that exists between frequency and wavelength

4 PT Inverse relationship

The number of nodes, antinodes and wavelengths shown below

5 PT 4 nodes, 3 antinodes and 1 ½ wavelengths

Sound waves and seismic waves represent this broad class of waves.

1 PT Mechanical waves

The tiny hairs in this part of the ear resonate to different frequency

2 PT The Cochlea

Changes in the tension or length of the vibrating medium causes this wave charcteristic to change

3 PT Pitch

It’s the beat frequency produced by 441 Hz and 448 Hz tuning forks

4 PT 7 beats per second

A radio wave is an example of this broad wave category

5 PT Non-mechanical wave

It’s the normal audible range of hearing for humans

1 PT 20 – 20,000 Hz

It’s the two terms used to describe frequencies above and below our normal range of hearing

2 PT Infrasound (below) and Ultrasound (above)

These types of waves travel slowest through solids and fastest through a vacuum

3 PT Non-mechanical waves (light waves or electromagnetic waves)

This wave phenomenon develops when the vibrations of one object match the natural frequency of another object, causing it to increase in amplitude.

4 PT resonance

This wave phenomenon occurs when two identical waves constructively and destructively interfere to form nodes and antinodes.

5 PT Standing waves
