The room temperature charges by a small amount from `T` to `T+DeltaT` (on Kelvin scale). The fundamental frequency of organ pipe changes from `f` to `f+Deltaf`, thenA. `(DeltaT)/(T)`B. `1/2(DeltaT)/(T)`C. `2(DeltaT)/(T)`D. `(-DeltaT)/(T)` |

Answer» Correct Answer - B `v prop sqrtT " and " n prop sqrtT` `(n+Deltan)/(Deltan) = sqrt((T+DeltaT)/(T))` `(n+Deltan)/(Deltan) = (1+(DeltaT)/(T))^(1/2)` `1+(Deltan)/(n) = 1+1/2 (DeltaT)/(T)` `(Deltan)/(n) = 1/2 (DeltaT)/(T)` |
