Question

determine which of the following must change when pitch gets higher a.amplitude b.frequency c.wavelength d.intensity e.speed of sound waves

Answer 1

Higher pitch means higher frequency.

But higher frequency also means shorter wavelength, because the product of (frequency) x (wavelength) is the wave-speed, so it doesn't change.

So (b) and (c) must both change.

Answer 2

Answer:

Th Correct Answer is C

Explanation:

Changing Pitch

• The four characteristics of the series that influence its frequency are density, diameter, tension, and length.
• These characteristics are illustrated below:
• While the length of a sequence is modified, it will reverberate with a distinct wavelength. Lower strings have a greater frequency and therefore more powerful pitch.
