Do you know an equation that relates the speed of a wave to the wavelength and frequency?

[soulja101]

is 17cm the wave length

[Kurdt]

What do you know about thewavelength of the fundamental frequency of a closed pipe?

[soulja101]

not much all i know is that there's some kind of pattern

[Kurdt]

for a pipe closed at one end the fundamental frequency has a wavelength 4 times the pipe length.
