Answer all the questions.
1 A flute is a musical instrument made from a long tube that is open at both ends.
A stationary sound wave in the tube produces a musical note.
The lowest frequency note that a standard flute produces in air is 262 Hz.
The speed of sound in air at a temperature of 20 °C is 340 m s–1.
(a) Show that a standard flute has an approximate length of 0.65 m.
[3]
(b) In an ideal gas, the speed v of sound is given by
⎛γRT⎞1/2
v= ⎝M⎠
where
γ is a dimensionless constant that depends on the gas
R is the molar gas constant
T is the absolute temperature
M is the molar mass of the gas.
The table below shows values of γ and M for both air and helium.
Gas γ M / g mol–1
Air 1.40 29.0
Helium 1.67 4.00
