Title: String Instruments

1
String Instruments
• In a stringed instrument, there are strings of
various thicknesses. Generally, for a given
material, the thicker the string the higher the
linear density. Which of the following is true
of these different strings? (Assume that the
tensions are similar.)
• The thickest string produces the highest
frequency, the thinnest string produces the
lowest.
• The thinnest string produces the highest
frequency, the thickest string produces the
lowest.
• None of the above.

String Instruments
• In a stringed instrument, a string is tuned by
changing its tension. If a string is playing
flat (too low a frequency), you should
• increase the tension.
• decrease the tension.
• None of the above.

String Instruments
• In some stringed instruments, there are frets you
can press the string against, to shorten the
length of string that is vibrating. By doing
this, you would
• increase the frequency and pitch.
• decrease the frequency and pitch.
• None of the above.

Speed of Sound
• The bulk modulus of air is proportional to the
Kelvin temperature of the air. If the Kelvin
temperature of the air increases by 1 (about 3
degrees near room temp), then
• the speed of sound in the air will increase by
1.
• the speed of sound in the air will decrease by
1.
• the speed of sound in the air will increase by
less than 1.
• the speed of sound in the air will decrease by
less than 1.
