The electromagentic waves do not transport

Options

A. energy
B. charge
C. momentum
D. information

Answer

### Step-by-Step Solution:

1. **Understanding Electromagnetic Waves**:
Electromagnetic (EM) waves are generated when charged particles accelerate. This acceleration creates a changing electric field, which in turn produces a magnetic field. The interplay between these fields results in the formation of EM waves.

2. **Energy in Electromagnetic Waves**:
The energy carried by EM waves is due to both the electric field (E) and the magnetic field (B). The energy density of the electric field is given by \( \frac{1}{2} \epsilon_0 E_0^2 \) and that of the magnetic field is given by \( \frac{1}{2} \mu_0 B_0^2 \).

3. **Momentum of Electromagnetic Waves**:
The momentum (p) of an EM wave is related to its energy (E) by the equation \( p = \frac{E}{c} \), where \( c \) is the speed of light. This indicates that EM waves can carry momentum and energy.

4. **What Electromagnetic Waves Cannot Transport**:
Although EM waves can transport energy, momentum, and information, they do not transport electric charge. This is because the waves are generated by charged particles, but the charge itself does not move with the wave.

5. **Conclusion**:
In summary, electromagnetic waves can transport energy, momentum, and information, but they do not transport charge.

### Final Answer:
Electromagnetic waves do not transport charge.
