Frequency=(speed of sound)/(wavelength)
that means
wavelength =(speed of sound )/(frequency)
speed of sound=344 m/s

4.
frequency=587. 33 Hz
thus
wavelength=344/587.33
=0.586 m

5.
frequency=493.88 nHz
thus
wavelength=344/493.88
=0.69653 m

6. Frequency= 698.46 Hz
wavelength= 344/698.46
wavelength=0.4925 m

9. Frequency =783.99 Hz
wavelength=344/783.99
wavelength=0.439 m
