Q: A sound source sends a wave of 600 Hertz. This produces a wavelength of 3 m. Speed of sound wave in this question is. . . . . . . . .
  • A. 1800 ms²
  • B. 1800 ms⁻¹
  • C. 1800 ms¹
  • D. 1800 ms⁻ ²
Correct Answer: Option B - Frequency (n) = 600 Hz Wavelength (λ) = 3m Wave velocity (v) = ? v = n λ (v = Frequency × wavelength) = 600 × 3 = 1800 ms⁻¹ Thus the speed of the sound wave will be 1800 ms⁻¹
B. Frequency (n) = 600 Hz Wavelength (λ) = 3m Wave velocity (v) = ? v = n λ (v = Frequency × wavelength) = 600 × 3 = 1800 ms⁻¹ Thus the speed of the sound wave will be 1800 ms⁻¹

Explanations:

Frequency (n) = 600 Hz Wavelength (λ) = 3m Wave velocity (v) = ? v = n λ (v = Frequency × wavelength) = 600 × 3 = 1800 ms⁻¹ Thus the speed of the sound wave will be 1800 ms⁻¹
