What are the basic preconditions for periodic motion?
How is a traveling wave initiated? What are the minimum
conditions for producing a traveling wave?
What is sound?
What things must be measured to describe periodic motion?
What is the relation between wave velocity,
frequency, and wavelength?
Describe and give examples of the four basic wave phenomena:
What determines the velocity of a traveling wave ?
Does the speed of sound in air depend upon sound pitch?
upon sound loudness?
How are "beats" produced? What is a "subjective tone"?
How does sound wave description compare to the
description of radio waves?
What is resonance? What is a standing wave?
What are the wavelength conditions for resonance
for a stretched string, an open cylindrical air
column,a closed cylindrical air column?
Describe the physical properties of the sound
which are being detected by the human ear when
it perceives pitch, loudness, and quality of sound.
Distinguish between longitutional and transverse
waves. Which characterizes sound in air? Under
what conditions can both types of waves occur?
|General Wave Properties
- 1. reflection
- 2. interference
- 3. refraction
- 4. diffraction
|Characteristics of Audible Sound
- 1. pitch = frequency
- 2. loudness related to intensity, sensitivity
- 3. quality (timbre)
What do you measure when you detect pitch?
How does the human ear detect pitch?
What is the difference between sound intensity and loudness?
What is measured by decibels?
How can the ear mechanism distinquish between vowel sounds?
