Question

what do Electromagnetic waves pass through

Answer 1

[AI-generated answer — Bot GPT 3.5]

Electromagnetic waves can pass through a vacuum, as they do not require a medium to propagate. They can also pass through materials such as air, water, glass, and some types of metals, depending on the frequency and intensity of the waves. However, materials with high electron density, such as metals and conductors, can block or reflect electromagnetic waves.
