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.
