I have been scratching my head all night about this problem...
A man standing close to an iron railing consisting of evenly-spaced uprights makes a sharp sound and hears a note of frequency 640hz. calculate the spacing between the uprights. (speed of sound in air = 330m/s)
perhaps one of you can help me out with this problem...
THANKS!
