Question

A sound wave is passing by a student 250 times every second. What is the frequency of the sound wave?

Answer 1

My answer i believe is simply 250 Hz, because sounds or vibrations travel in 1 cycle/second, meaning the number of cycles, in your case 250, divided by the time,1 second, will ultimately be 250 Hertz.  For every Cycle/second it will equal 1 Hz, so 250/1 = 250Hz

Answer 2

My answer is 250 Hz I believe this would be the answer because, its passing by the student 250 times a second.Though I might be wrong so please don't quote me on this if I am wrong.
