A pipe closed at one end is in resonance of a vibrating tuning fork when the length of the air column is 25 cm. The next resonance occurs when the length of the air column is 77 cm. If the speed of sound in air be 338 ms-1, then calculate the wavelength of the emitted note and the frequency of the fork.

A 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.
