Cross the odd one out

Options

A. Amplitude
B. Frequency
C. Voltage
D. Wave length

Explanation

To solve the question "Cross the odd one out," we need to analyze the given options and identify which one does not belong to the group based on their characteristics.

### Step-by-Step Solution:

1. **List the Options**: The options provided are:
- Option 1: Amplitude
- Option 2: Frequency
- Option 3: Voltage
- Option 4: Wavelength

2. **Identify Characteristics of Waves**:
- **Amplitude**: This is the maximum displacement of points on a wave from its rest position. It is a characteristic of waves.
- **Frequency**: This refers to the number of cycles of a wave that occur in one second. It is also a characteristic of waves.
- **Wavelength**: This is the distance between successive crests (or troughs) of a wave. It is another characteristic of waves.

3. **Analyze Voltage**:
- **Voltage**: This is a measure of the electric potential difference between two points in a circuit. It is not a characteristic of waves.

4. **Determine the Odd One Out**:
- Since Amplitude, Frequency, and Wavelength are all characteristics of waves, and Voltage is not related to wave motion, Voltage is the odd one out.

5. **Conclusion**:
- Therefore, the answer is **Option 3: Voltage**.
