Sections 1 & 2: Answer the following questions in your notebook:
1) A closed-end organ pipe is used to produce a mixture of sounds. The third and fifth harmonics in the mixture have frequencies of 1110 Hz and 1850 Hz respectively. What is the frequency of the first harmonic played by the organ pipe?
2) Don't miss Pipin' Pete live at City Park next weekend! He'll be featuring his new and improved, Poppin' Pipin' Playin' Machine! One of the closed-end pipes is capable of sounding out a first harmonic of 349.2 Hz. If the speed of sound in the pipe is 350 m/sec, what is the length of the air column inside the pipe?
3) Carla takes a 22.0-cm length of rigid, plastic tubing and places it into a glass of water so that one end of the tube is submerged 3.0-cm. She gently blows across the opposite end of the tube. What frequency sound waves will the tube produce? (The speed of sound at room temperature is 343 m/s)
