Speed of Sound is Maximum in Which Among the Following? A) Gases B) Vacuum C) Liquids D) Solids

The correct option is (D) SOLIDS.

 The speed of sound is greatest in solids and decreases as it moves from solids to liquids and liquids to gases. A vacuum cannot conduct sound. Sound travels at different speeds depending on the medium through which it passes. The speed of sound is also affected by temperature.

• When a vibration begins, the solid molecules collide immediately, and the compression wave travels quickly.
• The speed of sound is the distance travelled by any sound per unit of time.
• When the medium is dense, the molecules are tightly packed, implying that sound travels faster.
• As a result, as the medium density increases, so does the speed of sound.
