wavelenght

Question

The wavelength? w, in meters per? cycle, of a musical note is given by  w equals StartFraction r Over f EndFractionw= r  f ?,
where r is the speed of the sound in meters per second and f is the frequency in cycles per second. The speed of sound in air is 344 m divided by sec.344 m/sec.
What is the wavelength of a note whose frequency in air is 3232
cycles per? second? Round to the nearest tenth of a meter per cycle.

Answer 1

You just substitute the values of r=344 and f=3232 in the formula they already gave you: w= r / f (r divided by f) and you get the answer in meters. Then consider the rounding rules. In this case they ask you to round to the nearest tenth. For instance, 1.35 rounds to 1.4 and 1.32 rounds to 1.3 and so on.
