**Homework Statement**

A tuning fork of frequency 512 Hz is used to generate a standing wave pattern in a closed pipe, 0.850m long. A strong resonant note is heard indicating that an antinode is located

at the open end of the pipe.

frequency = 512Hz

length = 0.850m

a - What are the possible wavelengths for this note?

b - Which wavelength will give the most reasonable value for the calculation of the speed of sound in air?

Now this is for HW and i have the answer, but all I need is to know how to figure out how to get there. Ideas?

a - 3.40 m @ 1.74 x 10^3 m/s

1.13 m @ 580 m/s

0.680 m @ 348 m/s

0.486 m @ 249 m/s

b - 0.680m

Thanks.
