Answer to Problem 5PEA

The velocity of the sound wave is 343ms.

Explanation of Solution

Write the expression for the velocity of sound wave.

    v=fλ                                                                                        (I)

Here, v is the velocity of the sound wave, f is the frequency and λ is the wavelength.

Conclusion:

Substitute 256Hz for f and 1.34m for λ in equation (I) to find v.

    v=(256Hz)(1.34m)=(256Hz)(1s11Hz)(1.34m)=343.04ms343ms

Therefore, the velocity of the sound wave is 343ms.

Answer to Problem 5PEA

The velocity of the sound wave is 343ms.

Explanation of Solution

Conclusion:

Substitute 440.0Hz for f and 78.0cm for λ in equation (I) to find v.

    v=(440.0Hz)(78.0cm)=(440.0Hz)(1s11Hz)(78.0cm×102m1.0cm)=343.2ms343ms

Therefore, the velocity of the sound wave is 343ms.

Answer to Problem 5PEA

The velocity of the sound wave is 343ms.

Explanation of Solution

Conclusion:

Substitute 750.0Hz for f and 45.7cm for λ in equation (I) to find v.

    v=(750.0Hz)(45.7cm)=(750.0Hz)(1s11Hz)(45.7cm×102m1.0cm)=342.75ms343ms

Therefore, the velocity of the sound wave is 343ms.

Answer to Problem 5PEA

The velocity of the sound wave is 343ms.

Explanation of Solution

Conclusion:

Substitute 2500.0Hz for f and 13.7cm for λ in equation (I) to find v.

    v=(2500.0Hz)(13.7cm)=(2500.0Hz)(1s11Hz)(13.7cm×102m1.0cm)=342.5ms343ms

Therefore, the velocity of the sound wave is 343ms.
