Question

What can you say about the frequency of a wave that produces a high pitched noise?

Answer 1

The expression "high pitched noise" can be based upon the human hearing sense.  For humans, the hearing range of frequency can be defined from low to high, being low the ones with less cycles, or pressure waves per second, from 20 to 200Hz. By other side, high pitch requires much more cycles per second, from 4000 to 15000 Hz.

So "high pitched noise", or more correct "high pitch sound" is made of high frequencies, based on the human hearing.

Answer 2

Higher Pitch: Closer Parabolas/Higher Frequency

Lower Pitch: Further Parabolas/Lower Frequency

Answer 3

When we talk about the pitch of a sound/noise, we generally mean its frequency. So a noise that has a high pitch means that it has a high frequency, and thus a short period (frequency and period are inversely proportional to each other).

Answer 4

short ans is that higher pitch => higher frequency

but if you like to do math, let

Vs be speed of sound

L, wave length

F, frequency

imagine this coming at your ear

~~~~~~~~~~~~~~~~  > * | * <

imgine that's 15 kHz or 15,000 waves that hit your ear drums every second.

but the speed of sound, Vs = 340.29 m/s, so you need to pack 15000 waves, end-to-end into a space 340 m long, so they need to be short. how short?

about  340.29/15000 = 0.022686 m long.

this is the wavelenght, 2.27 cm.

Answer 5

higher pitch = higher frequency

shorter wavelength
