Question:
The solid medium in which speed of sound is greater ?
AGlass
BDiamond
CSteel
DIron
Answer:
B. Diamond
Explanation:
Speed of sound:
The speed of sound varies from substance to substance.
Typically, sound travels most slowly in gases, faster in liquids, and fastest in solids.
Sound travels fastest in solids because the molecules are tightly packed together, allowing sound waves to move faster
In exceptionally stiff materials such as diamond, sound travels at 12,000 m/s.
The speed of sound in steel is 6,000 meters per second.
Speed of sound in
Air : 340 m/s
Water : 1,480 m/s
Mercury : 1452 m/s
Glass : 5000 m/s
Aluminium : 5000 m/s
Iron : 5000 m/s
