Problem 28:
A 2.29-m long organ pipe acts as a closed-end resonator that produces several different harmonic frequencies in the audible range from 20 Hz to 20,000 Hz. Assuming a speed of sound of 343 m/s, determine the 5th highest frequency that the pipe can produce.

Habits of an Effective Problem Solver
-
Read the problem carefully and develop a mental picture of the physical situation. If necessary, sketch a simple diagram of the physical situation to help you visualize it.
-
Identify the known and unknown quantities and record in an organized manner, often times they can be recorded on the diagram itself. Equate given values to the symbols used to represent the corresponding quantity (e.g., v = 345 m/s, λ = 1.28 m, f = ???).
-
Use physics formulas and conceptual reasoning to plot a strategy for solving for the unknown quantity.
-
Identify the appropriate formula(s) to use.
-
Perform substitutions and algebraic manipulations in order to solve for the unknown quantity.
