Q: A sound wave produced at wavelength 2.5m, its frequency is 400 Hz. Find the velocity of wave.
  • A. 100m/s
  • B. 10m/s
  • C. 1000m/s
  • D. 10000m/s
Correct Answer: Option C - Frequency (f) = 400 Hz Wavelength (λ) = 2.5 m Speed of sound wave (v) = f x λ = 400 × 2.5 = 1000m/s
C. Frequency (f) = 400 Hz Wavelength (λ) = 2.5 m Speed of sound wave (v) = f x λ = 400 × 2.5 = 1000m/s

Explanations:

Frequency (f) = 400 Hz Wavelength (λ) = 2.5 m Speed of sound wave (v) = f x λ = 400 × 2.5 = 1000m/s
