The loudness and pitch of a sound note depend on

Options

  1. Aintensity and velocity
  2. Bfrequency and velocity
  3. Cintensity and frequency
  4. Dfrequency and number of harmonics

Correct answer

C. intensity and frequency

Step-by-step solution

The loudness depends on the amplitude of sound wave, thus it depends on its intensity. The pitch of a sound describes how low or high a note is produced by the instrument. Thus, it depends on the frequency of sound source.
