Step 1: Concept
Electromagnetic waves consist of oscillating electric and magnetic fields traveling through space. They are produced by accelerating charges but do not carry any mass or physical electric charge with them.
Step 2: Meaning
As electromagnetic waves propagate, they transfer energy, momentum, and information from the source to the receiver.
Step 3: Analysis
Because electromagnetic waves exert radiation pressure, they carry momentum. They also propagate heat and radiation energy (like sunlight) and are widely used to transmit signals (information). However, since they are neutral waves, they cannot transport electric charge.
Step 4: Conclusion
Therefore, charge is the physical quantity that is not transported by electromagnetic waves.
