The pitch of sound depends on

Options

A. frequency
B. amplitude
C. both of these
D. none of these

Answer

To determine what the pitch of sound depends on, we can follow these steps:

### Step 1: Understand the Terms
- **Pitch**: It is a characteristic property of sound that describes how high or low a sound is perceived.
- **Frequency**: It refers to the number of vibrations or cycles per second of a sound wave, measured in Hertz (Hz).
- **Amplitude**: It refers to the height of the sound wave, which determines the loudness of the sound.

### Step 2: Analyze the Relationship
- The pitch of a sound is directly related to its frequency. Higher frequency sounds are perceived as having a higher pitch (shriller sound), while lower frequency sounds are perceived as having a lower pitch (flatter sound).
- Amplitude, on the other hand, affects the loudness of the sound but does not influence the pitch.

### Step 3: Conclusion
- Since pitch is directly proportional to frequency, we conclude that the pitch of sound depends on frequency.

### Final Answer
The pitch of sound depends on **frequency**.
