Question

The wavelenght of a sound note is 1m in air and
2.5m in a liquid find the speed of sound in
the liquid, if the speed of sound in air
in 330mis​

Answer 1

Answer:

Velocity of sound waves=330m/s

Velocity of sound waves=330m/sΔϕ=KΔx

Velocity of sound waves=330m/sΔϕ=KΔxΔϕ= phone difference

Velocity of sound waves=330m/sΔϕ=KΔxΔϕ= phone differenceK= 2π/Δx= Path difference

Δx= Path differencePutting the values given in question-

Δx= Path differencePutting the values given in question-1.6π= λ/2π (100/40 )λ= 1.6π/2π× 10040×10 = 2/1 m

1 mNow,V=fλ330=f(2/1 )f=660Hz
