Problema Solution

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 the air is 344 m/sec. what is the wavelength of a note whose frequency in air is 45 cycles per second

Answer provided by our tutors

w=r/f

or wavelength = velocity/frequency

Here velocity = 344 m/sec.

Frequency = 45 hz.

So wavelength = 344/45 = 7.64 m.
