Concept explainers
To calculate:The velocity of sound in helium gas when a tuning fork is used with a resonating column.
Answer to Problem 13PP
Thevelocity of sound in helium gas is
Explanation of Solution
Given info:
Frequency of the tuning fork =
Resonance spacing =
Formula used:
The resonance lengths in a closed pipe are found at half-wavelength intervals.
Hence, the length-wavelength relationship:
In addition, the frequency is given by
Calculation:
As per problem,
Frequency of the tuning fork (
Resonance spacing (
To calculate wavelength use formula
Substitute the value
To calculate velocity of sound in helium rearrange the formula
Substitute the values
Conclusion:
Thus, thevelocity of sound in helium gas is
