Use the links below to access specific internet content
for Sound and Music. The internet content is available at
the GBS Physics web site as well as from other external
sites. (Please notify the instructor of any broken links.
- A detailed discussion of the nature of a sound wave,
including a discussion of sound as a
mechanical wave, a
longitudinal wave, and a
pressure wave. Start in Lesson
1a of the Physics Classroom.
- A detailed discussion of the various wave properties
and our ability to detect them, including frequency
and pitch, intensity
(and the deciBel
scale), and speed
(including a discussion of what an echo is). Start in
Lesson 2a of
The Physics Classroom.
- A detailed discussion of various wave behaviors,
Doppler effect, wave
interference, and beats.
Start in Lesson
3a of The Physics Classroom.
- A detailed discussion of resonance and standing waves
which makes an excellent complement to in-class
demonstrations and lecture; topics include natural
vibration and resonance, standing
wave patterns, and harmonics.
Start in Lesson
4a of The Physics Classroom.
- A detailed discussion of resonance and the
mathematics and physics of musical instruments; again,
this provides an excellent companion to in-class
demonstrations and lecture; topics include resonance,
air columns; and closed
-end air columns. Start in Lesson
5a of The Physics Classroom.
- Two online animations demonstrating how a
longitudinal sound wave can be produced by the vibration
of an object - by a
tuning fork and by a
guitar string. Compressions and rarefactions are
- Online animation demonstrating the
distinction between an echo and a reverberation.
Explains the significance of that magical 17 meters; once
enlightened, you will begin singing in the shower.
- Online animations of the vibration of a guitar string
in its various harmonic modes - first,
harmonics. Wave patterns are shown and nodes and
antinodes are located.
- Finally, there is a unit review at the Review
Session and there are some sample quizzes at the
Still under construction.
