The fundamental frequency of a closed pi...

The fundamental frequency of a closed pipe is 293 Hz when the air in it is at a temperature of `20^@C`. What will be its fundamental frequency when the temperature changes to `22^@C` ?

Text Solution

Verified by Experts

The correct Answer is:
B, D
We know that for frequency f
T=temperature
`fpropsqrtT`
so, `f_1/f_2=sqrtT_1/sqrtT_2`
`rarr 293/f_2=sqrt293/sqrt295`
`rarr f_2=(293xxsqrt295)/sqrt293=294Hz`
