The phase speed of sound in air can be calculated using the formula:
υ = λ / Т, where υ is the speed of sound propagation in air (υ = 331 m / s), λ is the length of the sound wave (λ = 668 m), T is the period of the sound wave (s).
Let us express and calculate the period of the sound wave:
Т = λ / υ = 668/331 ≈ 2 s.
Answer: The period of the sound wave is 2 s.
