Question

Answer

The Relationship Between Frequency and Pitch
When discussing sound, two crucial concepts are frequency and pitch. The frequency of a sound wave refers to how many vibrations occur per second, measured in Hertz (Hz).

Understanding Pitch
- **Pitch** is the perceptual quality that allows us to classify sounds as high or low. It directly correlates with the frequency of the sound waves:
- **Higher Frequency**: More vibrations per second.
- **Lower Frequency**: Fewer vibrations per second.

Impact of Frequency on Sound Characteristics
- When the frequency increases:
- The **pitch** becomes **higher**.
- The sound is perceived as **sharper** or **shriller**.
- Conversely, a lower frequency results in:
- A **lower pitch**.
- A **deeper** or **more resonant** sound.

Examples for Clarity
- Instruments produce various pitches based on their frequency:
- A **flute** (high frequency) produces a **high pitch** sound.
- A **tuba** (low frequency) produces a **low pitch** sound.

Conclusion
In summary, the relationship between frequency and pitch is fundamental in understanding sound. Therefore, the statement 'Higher the frequency of vibration, the **higher** the pitch, and shriller the sound' is accurate, making **option 'B'** the correct choice. Higher frequencies lead to higher pitch and sharper sounds, while lower frequencies result in lower pitches and deeper sounds.

Answer

The higher the frequency of vibration, the higher the pitch and shriller the sound. This means that sounds with higher frequencies are perceived as higher-pitched and more piercing.

Answer

Yes, a higher frequency of a sound wave results in a higher pitch and a shriller sound:

*Explanation*
The pitch of a sound is the frequency of the sound waves that the human ear can perceive. A higher frequency of vibration results in a higher pitch and a shriller sound.

*Examples*
A child's scream or a mosquito's buzz are examples of low pitch sounds, while a lion's roar or a drum beat are examples of high pitch sounds.

*Other characteristics of sound*
In addition to pitch, sound also has other characteristics, such as loudness and tone. Loudness is determined by the amplitude of the sound wave, while tone quality is what differentiates pitch and loudness.

*Human hearing*
The human ear can only identify sounds with a frequency between 20–20,000 Hz. Sounds that are louder than 130 decibels can permanently damage the human ear.

The amplitude of vibration of a sound wave determines its pitch. The higher the frequency of the sound wave, the lower is its pitch, and hence shriller is the sound produced. Similarly, a sound wave of lower frequency has a low pitch and hence a shriller sound is produced.

Answer

Because frequency depend on pitch and loudness depend on amplitude
Frequency depend on pitch it means higher the frequency the pitch is also higher
but frequency is lower the pitch is also lower so option b correct answer
