Question

Solve the problem. Be sure to show all of your work.

The wavelength, w, in meters per cycle, of a musical note is given by

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.

Answer 1

(wavelength)*(frequency)=(speed)

Wavelength=344/45=7.6 m per cycle.
