प्रश्न
In which medium the speed of sound is more: humid air or dry air? Give a reason to your answer.
उत्तर १
Speed of sound is more in humid air because in presence of moisture, the density of air decreases and sound travels with greater speed.
`"V" ∝ 1/sqrt("ρ")`
उत्तर २
The speed of sound is more in the humid air as compared to dry air. Because the air moisture decreases the density of air and speed of sound is inversely proportional to the density of air. So, sound travels faster in the humid air.
