a solid.

Reason: electromagnetic wave speed in a medium is v = c/n, so waves are slowed by the medium's refractive index. Solids typically have much higher refractive indices (stronger polarization) than gases, so EM waves travel more slowly through solids. (Caveat: exact speed depends on the specific material; vacuum is fastest.)
