[Intro]
The waves roll in
The waves roll out
The sound is found
(Rolling in the waves)
All around
(Oh, the souls it saves)
[Verse 1]
Taking it in
Shouting it out
Listening
Petitioning
[Chorus]
Parallel to the direction
(Of wave propagation)
Through a medium
(Hearing premium)
[Bridge]
The waves roll in
The waves roll out
The sound is found
(Rolling in the waves)
All around
(Oh, the souls it saves)
[Verse 2]
Reaching my hear
So that I can here
Out of my lips
Making the trip
[Chorus]
Parallel to the direction
(Of wave propagation)
Through a medium
(Hearing premium)
[Bridge]
The waves roll in
The waves roll out
The sound is found
(Rolling in the waves)
All around
(Oh, the souls it saves)
[Chorus]
Parallel to the direction
(Of wave propagation)
Through a medium
(Hearing premium)
[Bridge]
The waves roll in
(The waves roll out)
The sound is found
(All around)
[Outro]
Rolling in the waves
(Oh, the souls it saves)
A SCIENCE NOTE
Sound waves can be classified into several types based on various characteristics. Here are the primary types:
1. Longitudinal Waves
- Description: In longitudinal waves, the particle movement is parallel to the direction of wave propagation.
- Example: Most sound waves in air, liquids, and gases are longitudinal. When you speak, the air molecules vibrate back and forth in the same direction as the sound wave.
2. Transverse Waves
- Description: In transverse waves, particles move perpendicular to the direction of wave propagation. These are less common in sound.
- Example: While sound typically doesn’t form transverse waves in air, it can occur in solid materials, like vibrations on a string or surface.
3. Surface Waves
- Description: Surface waves occur at the interface between two different media, like air and water. They combine both longitudinal and transverse motion.
- Example: Earthquake waves (seismic waves) can be an example, where sound travels on the surface of the Earth.
4. Mechanical Waves
- Description: Sound is a type of mechanical wave because it requires a medium (air, water, or solid) to travel through. Mechanical waves involve the transfer of energy through the oscillation of particles in the medium.
- Example: All everyday sounds are mechanical waves because they need air or another medium to propagate.
5. Electromagnetic Waves
- Description: These waves do not require a medium to propagate and can travel through a vacuum. Sound is not an electromagnetic wave, but this is a general wave classification.
- Example: Radio waves, microwaves, and light waves are all examples of electromagnetic waves.
6. Infrasonic Waves
- Frequency Range: Below 20 Hz (too low for human hearing).
- Example: Earthquake waves, elephant communication, and volcanic activity produce infrasonic waves.
7. Audible Waves
- Frequency Range: Between 20 Hz and 20,000 Hz (the range that humans can hear).
- Example: Music, speech, and everyday sounds.
8. Ultrasonic Waves
- Frequency Range: Above 20,000 Hz (too high for human hearing).
- Example: Used in medical imaging (ultrasound), cleaning, and animal echolocation (e.g., bats and dolphins).
9. Shock Waves
- Description: These are a type of highly intense, sudden sound wave that occurs when an object moves faster than the speed of sound, compressing sound waves into a single, powerful wave.
- Example: Sonic booms from supersonic aircraft.
These classifications of sound waves vary based on frequency, direction of particle motion, and the medium through which they travel.
