Wave Speed Physics Example 5

Solution

1. 1
   Recall the wave equation: $v = f \lambda$, where $v$ is wave speed, $f$ is frequency, and $\lambda$ is wavelength.
2. 2
   Substitute the given values: $v = 440 \times 0.773$.
3. 3
   Calculate: $v = 440 \times 0.773 = 340.12 \text{ m/s}$.
4. 4
   Round appropriately: $v \approx 340 \text{ m/s}$, which is consistent with the speed of sound in air at room temperature.
