0.75 cm

long closed organ pipe is vibrating in its fundamental mode. If the temperature of the room be

15 ° C

and the speed of sound in air at this temperature be

340 {ms}^{- 1}

, then determine the frequency of the note of the pipe. If the temperature rises to

25 ° C

, then what will be the frequency? Consider the effect of temperature on the length of the pipe negligible.
