Velocity of sound is maximum in:
Correct answer: D. Steel
- A. Air
- B. Water
- C. Vacuum
- D. Steel
Explanation
The reason why the velocity of sound is highest in steel is because steel is a denser medium than air, water, or vacuum. The denser the medium, the faster the sound waves can travel through it.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
