Part 1
A 3m long pipe is in a room where the temperature is 20 degrees C. What is the frequency of the first harmonic if the pipe is closed at one end?

Part 2
sound traveling in air at 23 degrees C enters a cold front where the air temp is 2 degrees C. If the sound frequency is 1500 Hz determine the wavelength in the colder air and in the warmer air, respectively.

Part 3
The speed of an ultrasonic sound of frequency 45KHz in air is 342 m/s what is the air temp?
