A piano emits frequencies the range from a low of about 28 Hz to a high of about 4200 Hz. Find the range of wavelengths in air attained by this instrument when the speed of sound in air us 340 m/s.
v=wave velocity , f= frequency, λ=wavelength Use it to find corresponding wavelengths for f=28 Hz λ= v/f= 337/28=12.036 m
for f=4200 Hz λ= v/f=337/4200= 0.08 m So max. wavelength is 12.036 m and Min Wavelength is 0.08 m So the range is between .08 m and 12.036 m Hope this helps.
