Question

An organ pipe, open at both ends, resonates at its first resonant length with a frequency of 128 Hz. What is the length of the pipe if the speed of sound is 346m/s?

Writeacher's comment: Telling a tutor "ASAP" or any other similar command is quite rude. Please don't do so in the future.
pipe is half a wave long? (must be, antinode at both ends.)
what is period of this wave?
T = 1/f = 1/128 second
goes a wavelength in 1/128 second
346 m/s (1/128) = wavelength
so wavelength = 346/128 meters
so
1/2 wavelength = 346 /256 meters

Do not hurry me. I get very nervous and upset.
