High-frequency electromagnetic waves generally penetrate materials differently than low-frequency waves, with penetration depending on the interaction between the waves and the medium. While high-energy waves can penetrate more, the skin effect in metals shows that higher frequencies actually penetrate less deeply. The transparency of materials, such as glass, is determined by how electromagnetic radiation interacts with the material's atomic structure. The electromagnetic spectrum is vast, and no single rule governs penetration across all frequencies and materials. Ultimately, the penetration ability of electromagnetic waves varies based on frequency and the specific properties of the medium.
