AM, which operates at a lower frequency, has radio waves with larger wavelengths, meaning they travel farther but struggle to penetrate solid objects like buildings.

Aren’t low frequencies better at penetrating materials?

Yes. But any metal in the building that's smaller than the wavelength of the AM radio frequency which is quite long, will absorb the radio wave so it won't penetrate the building
