Pitch of sound is determined by its

Options

A. frequency
B. speed
C. amplitude
D. loudness

Answer

To determine the pitch of sound, we need to understand the factors that influence it. Here’s a step-by-step solution to the question:

### Step 1: Understand the concept of pitch
- **Definition**: Pitch is a property of sound that allows us to differentiate between sounds. It describes how high or low a sound is perceived.

### Step 2: Identify the factors affecting pitch
- **Frequency**: The pitch of a sound is primarily determined by its frequency. Frequency refers to the number of vibrations or cycles per second of a sound wave, measured in Hertz (Hz).
- **Amplitude**: This refers to the loudness or intensity of the sound and does not affect the pitch.
- **Speed**: The speed of sound can vary depending on the medium (air, water, etc.) but does not influence the pitch itself.
- **Loudness**: This is related to the amplitude of the sound wave and is separate from pitch.

### Step 3: Analyze the options
- Given the options, we need to find which one correctly states what determines the pitch of sound.
- Since we established that pitch is determined by frequency, we can conclude that any option stating otherwise (like amplitude or speed) is incorrect.

### Step 4: Conclusion
- The correct answer is that the pitch of sound is determined by its **frequency**.

### Final Answer
- **The pitch of sound is determined by its frequency.**
