Electromagnetic (EM) waves are not charged because they do not carry an electric charge. Light, which is composed of EM waves, does not cause objects to become charged when exposed to it, supporting the idea that EM waves themselves are neutral. While EM waves consist of oscillating electric and magnetic fields, these fields can influence charged particles without the waves being charged. The distinction lies in the nature of the waves, which are fundamentally different from charged particles. Therefore, EM waves remain uncharged despite their ability to interact with charged matter.
