Options

A. zero
B. `pi`
C. `pi//2`
D. `pi//4`

Explanation

To solve the question regarding the phase difference between the magnetic and electric field vectors in electromagnetic waves, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Electromagnetic Waves**:
Electromagnetic waves consist of oscillating electric (E) and magnetic (B) fields that are perpendicular to each other and to the direction of wave propagation.

2. **Graphical Representation**:
To visualize the relationship between the electric and magnetic fields, we can use a three-dimensional graph. Assume:
- The x-axis represents the magnetic field (B).
- The z-axis represents the electric field (E).
- The y-axis represents the direction of wave propagation.

3. **Identifying Peaks**:
In the graph, we can observe that the peaks of the electric field and the magnetic field occur simultaneously. This means that when the electric field reaches its maximum value, the magnetic field also reaches its maximum value at the same point in time.

4. **Analyzing Zero Amplitude**:
Similarly, when the electric field's amplitude is zero, the magnetic field's amplitude is also zero at the same time. This indicates that both fields reach their maximum and minimum values together.

5. **Conclusion on Phase Difference**:
Since the peaks and zero crossings of the electric and magnetic fields occur at the same time, we conclude that the phase difference between the electric and magnetic field vectors in electromagnetic waves is zero.

### Final Answer:
The phase difference between the magnetic and electric field vectors in electromagnetic waves is **0 radians**.
