Question 441615
The wavelength, w, in meters per cycle, of a musical note is given by 
w=r/f 
where r is the speed of sound in meters per second and f is the frequency in cycles per second. The speed of sound in air is 344 m/sec. 
----------------
What is the wavelength of a note whose frequency in air is 45 cycles per second? Round to the nearest tenth of a meter per cycle 
--------------------
w = (344 m/sec]/[45 cycles/sec]
---
w = 7.6444 meters/cycle
