Our ear can hear the frequency of sound waves

Options

A. 20 to 20,000 cycles/sec
B. 1000 to 2000 cycles/sec
C. 5000 to 7000 cycles/sec
D. 5000 to 10,000 cycles/sec

Explanation

**Step-by-Step Solution:**

1. **Understanding Sound Frequency**: Sound waves are characterized by their frequency, which is measured in Hertz (Hz). Frequency refers to the number of cycles per second of a sound wave.

2. **Human Hearing Range**: The human ear can detect sound frequencies ranging from 20 Hz to 20,000 Hz (20 kHz). This means we can hear sounds that oscillate between these frequencies.

3. **Identifying the Correct Range**: The question provides several options for the frequency range that the human ear can hear. We need to identify which of these options matches the known range of human hearing.

4. **Evaluating the Options**:
- Option 1: 20 to 20,000 cycles per second (Correct)
- Option 2: 1,000 to 2,000 cycles per second (Incorrect)
- Option 3: 5,000 to 7,000 cycles per second (Incorrect)
- Option 4: 5,000 to 10,000 cycles per second (Incorrect)

5. **Conclusion**: The correct answer is that the human ear can hear sound frequencies from 20 to 20,000 cycles per second.

**Final Answer**: The human ear can hear sound frequencies ranging from 20 to 20,000 cycles per second.
