Problem 1E

The speed of sound in air at 20o C is 344 m/s. (a) What is the wavelength of a sound wave with a frequency of 784 Hz, corresponding to the note G5 on a piano, and how many milliseconds does each vibration take? (b) What is the wavelength of a sound wave one octave higher (twice the frequency) than the note in part (a)?

Step 1 of 3

9/7/2016 3.3 Hearing What do we hear  Sound waves: vibrations of air o Just like we don’t see all the possible wavelengths of light out there, we also don’t hear all the frequencies of possible sound waves. o We hear between 20­20,000 Hz (cycles per second) Features of sound 1. Pitch (low, high, medium tone) o Corresponds...
