Question

the frequency if a piano note is 261.63 Hz. What’s the wave length in centimeters if the speed of air is 343.06m/s

Answer 1

$wavelength=\frac{speed}{frequency}$

$wavelength=\frac{343.06}{261.63}=1.31m$

converting it into centimeters as 1m=100 cm

hence wavelength in cm = 1.31 x 100 =131cm
