- Liquid
- Gas
- Vacuum
- Solid
Why do sound travel faster in solids compared to liquids and gases
- solids
- gases
- vacuum
- liquids
- v=λ + ν
- v=λ - ν
- v=λ×ν
- λ=v×ν

A man stands before a large wall at a distance of and claps his hands at regular intervals. Initially, the interval is large. He gradually reduces the interval and fixes it at a value when the echo of a clap merges with the next clap. If he has to clap during every, find the velocity of sound in air.
How is frequency measured?
In which medium sound travels faster: air or iron?
Two children are at opposite ends of an aluminum rod. One strikes the end of the rod with a stone. Find the ratio of times taken by the sound wave in the air and in aluminum to reach the second child (velocity of sound in rod).
- speed of sound is equal to speed of light
- speed of sound is less than speed of light
- speed of soundis greater than speed of light
- speed of soundis less than or equal to speed of light
