Which of the following properties of sound waves determines how loud or
soft a sound is?
O
A. Pitch
O
B. Wavelength
O
C. Frequency
O
D. Amplitude
SUBMIT

D. Amplitude

Explanation:

The amplitude of sound waves determines how loud or soft a sound is. The loudness of a sound is a function of its amplitude.

Amplitude is defined as the maximum displacement of wave from its source.

The amplitude of a sound wave determines how loud the sound can be heard.

A wave with a large amplitude will have a large loudness. Waves of low amplitude will also show softness.

Amplitude is one of the fascinating properties of waves.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
