Question

the velocity of sound is greatest in: the option is water, air, vacuum, metal

Answer 1

sound travels fastest in a metal or any other solid as the atoms and molecules are tightly packed which allows the sound waves to travel faster and smoothly without decreasing it's energy

Answer 2

Answer:

The velocity of sound is the greatest in metal.

Explanation:

• Sound is a longitudinal wave
• In longitudinal waves, all particles vibrate in the same direction as the wave
• There are regions of compression and rarefaction
• Regions of compression are those where particles are closely packed and have little space between each other
• Regions of rarefaction are those where particles are far away from each other
• The distance between the point of compression and rarefaction is called the amplitude
• The speed of the sound is the greatest in solids as the molecules in solids are closer to one another and they can vibrate faster, so the sound wave can travel faster

The velocity of sound is the greatest in metals.
