The frequency of a wave is 5 Hz. It refers to (type of wave)

Options

A. ultrasonics
B. microwaves
C. infrasonics
D. radio waves

Answer

To determine the type of wave corresponding to a frequency of 5 Hz, we can follow these steps:

### Step 1: Understand the Frequency Range of Different Waves
- **Ultrasonic Waves**: Frequencies greater than 20 kHz (20,000 Hz).
- **Microwaves**: Frequencies ranging from 1 GHz to 1000 GHz (1 GHz = 1,000,000,000 Hz).
- **Infrasonic Waves**: Frequencies less than 20 Hz.
- **Radio Waves**: Frequencies ranging from 3 kHz to 300 GHz.

### Step 2: Identify the Given Frequency
- The frequency given in the question is 5 Hz.

### Step 3: Compare the Given Frequency with the Ranges
- Since 5 Hz is much less than 20 Hz, we compare it with the infrasonic range.

### Step 4: Classify the Wave
- Since 5 Hz is less than 20 Hz, it falls into the category of infrasonic waves.

### Conclusion
- Therefore, the type of wave with a frequency of 5 Hz is classified as an **infrasonic wave**.
