The speed of sound in a metal is approximately:
Correct answer: B. 5000 m/s
- A. 1500 m/s
- B. 5000 m/s
- C. 330 m/s
- D. 50 m/s
Explanation
Correct option is B.The speed of sound in metal is approximately 5000 meters per second.The speed of sound in solid is 6000 meters per second, while the speed of sound in steel is equal to 5100 meters per second. Another interesting fact about the speed of sound is that sound travels 35 times faster in diamonds than in the air.Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air.

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.
