Question

High-frequency sound waves have a shorter (amplitude, pitch, wavelength) and a higher (amplitude, pitch, wavelength) than low-frequency sound waves.

Answer 1

the most appropriate answers are ...

high frequency sound has shorter wavelength !

a higher pitch than low frequency...!!

so , wavelength and pitch !!

Answer 2

Answer: High-frequency sound waves have a shorter wavelength and a higher pitch than low-frequency sound waves.

Explanation:

For wave moving in a particular medium, its seed is constant. The wavelength of the wave is inversely proportional to the frequency. The pitch is the quality of sound which directly proportional to the frequency. Higher the frequency, higher is the pitch.

Thus, a high frequency sound wave would have shorter wavelength and higher pitch as compared to a low frequency sound waves.
