# Resonant Frequencies in Open-Closed Pipe

APPH12-DJTUVR

Consider a pipe (open on one end, closed on the other) of length $1.5$ $m$. A sound wave ($v$ $=$ $340$ $m/s$) is directed down the tube. What are the first three resonant frequencies produced as a result of standing waves in the pipe?

A

$113.3$ $Hz$, $226.7$ $Hz$, $340$ $Hz$

B

$113.3$ $Hz$, $340$ $Hz$, $566.7$ $Hz$

C

$56.7$ $Hz$, $170$ $Hz$, $283.3$ $Hz$

D

$56.7$ $Hz$, $113.3$ $Hz$, $170$ $Hz$
