Purpose:
To calculate the speed of sound in air.
Equipment: See Lab 13.2 on page 479 in Physics: Concepts and Connections
Procedure: See Lab 13.2 on page 479 in Physics: Concepts and Connections
Data:
Frequency of tuning fork
1000 Hz
512 Hz
Length of air column (L)
0.07 m
0.1425 m
Diameter of tube (D)
0.025 m
0.025 m
Temperature (T)
22.5 C
22.5 C
Analysis:
For 1000 Hz tuning fork:
λ = 4(L + 0.3D)
= 4(0.07 m + 0.3(0.025 m)
= 0.31 m
For 512 Hz tuning fork:
λ = 4(L + 0.3D)
= 4(0.1425 m + 0.3(0.025 m)
= 0.6 m
For 1000 Hz tuning fork:
V = λf
= (0.31 m)(1000 Hz)
= 310 m/s
For 512 Hz tuning fork:
V = λf
= (0.6 m)(512 Hz)
= 307.2 m/s
Vs = 332 m/s + 0.6T
= 332 m/s + 0.6(22.5C)
= 345.5 m/s
For 1000 Hz tuning fork:
Error = Experiment value – Expected Value x 100%
Expected Value
= 307 m/s – 345.5 m/s x 100%
345.5 m/s
= -11.1%
For 512 Hz tuning fork:
Error
