Report on Laboratory Experiment "Air Column Resonance: The Speed of Sound"

A.Speed of Sound from Air Column Resonance

Tuning fork 1Frequencyf₁=512Hertz

Node Location (meters)	(meters)	l1(meters)	v1(meters per second)
L1= 0.19	= 0.53- 0.19=		=
L2= 0.53

Tuning fork 2Frequencyf₂=440Hertz

Node Location (meters)	(meters)	l2(meters)	v1(meters per second)
L1= 0.21	= 0.60- 0.21 =		=
L2= 0.60

The average speed of soundv_ave:

_______________________ meters per second

B.Speed of Sound from Temperature Equation

Air temperature in Celsius degrees(Room Temperature)T_air=20C.

Speed of Soundv_Tfrom Temperature Equation (accepted speed of sound):

v_T= 331.5 +0.6T_air= (meters per second).

1.What is the sound speed at temperatureof2C.

2.What is the sound speed at temperature of25C.

3.How to explain, that speed of sound depends on temperature?
