Which of the following is not transported by electromagnetic waves?

Options

A. Energy
B. Momentum
C. Charge
D. Information

Answer

To determine which of the following is not transported by electromagnetic waves, we will analyze each option: energy, momentum, charge, and information.

### Step-by-Step Solution:

1. **Understanding Electromagnetic Waves**:
Electromagnetic waves consist of oscillating electric and magnetic fields that propagate through space. They can carry various physical quantities.

2. **Analyzing Option 1: Energy**:
Electromagnetic waves carry energy. For example, when light strikes a metal surface, it can cause the emission of electrons due to the photoelectric effect, demonstrating that energy is indeed transported by electromagnetic waves.

**Hint**: Think about how light can cause physical changes, like heating or causing chemical reactions.

3. **Analyzing Option 2: Momentum**:
Electromagnetic waves also carry momentum. When light hits a surface, it exerts pressure, which is a manifestation of momentum transfer. This can be observed in phenomena such as solar sails used in space exploration.

**Hint**: Consider how light can push objects, like how a laser can exert force on a small particle.

4. **Analyzing Option 3: Charge**:
Electromagnetic waves do not transport charge. While they can influence charged particles (like electrons), the waves themselves do not carry charge. This is a fundamental property of electromagnetic radiation.

**Hint**: Recall that electromagnetic waves are neutral and do not have mass or charge associated with them.

5. **Analyzing Option 4: Information**:
Electromagnetic waves can carry information, especially in the context of communication technologies (like radio waves transmitting signals). This is evident in how radio and television broadcasts work.

**Hint**: Think about how we use radio waves to send messages over long distances.

6. **Conclusion**:
After analyzing all options, we can conclude that the correct answer is **charge**. Electromagnetic waves do not transport charge.

### Final Answer:
The option that is not transported by electromagnetic waves is **charge**.
