The frequency (f), wavelength \lambda and speed (v) of a sound wave are related as
- A. \( f=v\lambda \)
- B. \( \lambda=vf \)
- C. \( f=\frac{\lambda}{v} \)
- D. \( v=\lambda f \) ✓
Correct Answer: D. \( v=\lambda f \)
Explanation
The wave equation relates the speed of a wave to its frequency and wavelength by the formula v = fλ.
