Question

A sound wave travels at 340 meters/sec, with a pitch (frequency) of 260 Hertz. What is its wavelength in meters?

Answer 1

herz units are typically radians/second. set up the equation to have the "second" cancel, leaving only meters per radian.

$\frac{340 \: meters}{second} \times \frac{1 \: second}{260 \: rad} = 1.31 \: meters$

the radian is actually unitless here, so it is not written in the final answer.
