COMEDK · Physics · 16. Waves and Sound
The loudness and pitch of a sound note depends on
- A intensity and frequency
- B frequency and number of harmonics
- C intensity and velocity
- D frequency and velocity
Answer & Solution
Correct Answer
(A) intensity and frequency
Step-by-step Solution
Detailed explanation
Pitch is dependent on the frequency of the source of sound whereas loudness depends upon the amplitude of sound wave. Hence, the loudness and pitch of a sound note depends on intensity and frequency.
