I have a question and the answer, but I need to know how to get to the answer. Thanks

What is the frequency, in hertz, of a sound wave (v=340 m/s) with a wavelength of 0.20 m? answer is 1.7 103 Hz (there is a box symbol after 1.7 and the 3 is superscript)

• Physical Science -

v = fw
340 = f*0.2
f = 340/0.2 = ??
