Is Gravity and Light on the Same Spectrum?

Gravity operates as a wave, a in the physical realm. That could mean that chalon is giving mass to her illusions by mani manipulating those gravity waves. Someone who was better at the physics hit me up and juste confirmd or deny, that gravity and light are too different till they said to be on the same spectrum. I devily don't know enough to exactly way in on that pes. Anyway, just interesting thought.
