Question

The pitch of a sound is how high or low it is. The higher the frequency of a sound wave is, the higher its pitch. Each of the waves below represents a sound wave. Put the waves in order from lowest to highest pitch ​

Answer 1

The pitch of a sound is how high or low it is. The higher the frequency of a sound wave is, the higher its pitch.

Each of the waves below represents a sound wave. Put the waves in order from lowest to highest pitch.

Step-by-step explanation:

Answer 2

The waves in order from lowest to highest pitch ​: picture 1,2,3,4

Further explanation

Wavelength : from the crest to the crest of the next wave or the trough to the trough

Frequency (f): number of waves in one second

Can be formulated :

`\tt v=\lambda* f\\\\f=(v)/(\lambda)`

So the frequency is inversely proportional to the wavelength

The smaller the wavelength the greater the frequency and the greater the pitch

From the picture above (transverse wave), we determine the wavelength that is formed: ⇒1 wavelength =one crest (peak) + trough (base)

wavelength = distance : wave(distance = 4)

`\tt 1\rightarrow 1(1)/(2)~wave\rightarrow \lambda=(4)/(1(1)/(2) )=2.67 \\\\2\rightarrow 2~wave\rightarrow \lambda=(4)/(2)=2 \\\\3\rightarrow 2(1)/(2)~wave\rightarrow \lambda=(4)/(2(1)/(2) )=1.6\\\\4\rightarrow 3~wave\rightarrow \lambda=(4)/(3)=1.33`

So picture 1 has the largest wavelength, so it has the smallest frequency and the smallest pitch
