What happens when you increase the frequency of a sound wave?

Answer 1

Speed = distance / time [m /s]

likewise:

Speed of wave = wavelength x frequency [m /s]

Since sound waves travel at a fixed speed through a medium* a drop in frequency must cause a corresponding increase in wavelength

*Not always true. In water of example, lower frequency waves travel faster than higher frequency waves. When this happens the waves are said to be travelling through a dispersive medium.

Answer 2

Increasing the frequency of a sound wave will result in a higher pitch. This means the sound wave will have more oscillations per second, which creates a perception of a higher frequency.

Answer 3

The length of the sound wave decreases. And if there's anybody around

to hear it, it's perceived as a higher pitch than it was originally.

Answer 4

Well if you thought about it the pitch increases.

Answer 5

The Wavelength of the Sound Decreases. The most easily recognized effect is that the Pitch of the sound is Higher to the ear.

Answer 6

Along with amplitude, being one of the key measurements of sound, the frequency of a sound wave affects the perceived pitch of the sound. As the frequency increases, the pitch becomes higher.

Answer 7

Loudness is not the same thing as frequency, which relates to pitch, rather than loudness. So sound can increase without changing its frequency.

Answer 8

The length of the wave decreases.

Answer 9

the wavelength decreases

Answer 10

Higher frequency= higher pitch
