Question

What is the effect o f humidity on sound waves when humidity increases? (A) Speed of sound waves is more (B) Speed of sound waves is less (C) Speed of sound waves remains same (D) Speed of sound waves becomes zero

Tardigrade Admin · Accepted Answer

Velocity of sound =√(&gamma; R T/M) When water vapour are present in air, average molecular weight of air decreases and hence velocity increases.

Q. What is the effect o f humidity on sound waves when humidity increases?

Speed of sound waves is more

Speed of sound waves is less

Speed of sound waves remains same

Speed of sound waves becomes zero

Velocity of sound $= \frac{γ RT}{M}$
When water vapour are present in air, average molecular weight of air decreases and hence velocity increases.
