Sound travels faster in _________.
-
sea water
-
mercury
-
kerosene
-
none of these
A
Correct answer
Explanation
Sound travels fastest in denser media. Among the options, seawater (density ~1025 kg/m³) is the densest and sound travels at approximately 1530 m/s in seawater. Mercury is denser but sound doesn't propagate well in it due to high impedance. Kerosene is less dense than seawater.
