The light bulb glows because the resistance of the filament has reduced the electrical power. Vapor is steam or moisture that travels at a faster rate of vibration than water, into which it condenses as the vibrations are reduced. Water can become solid as the temperature falls, at which time it has an even lower rate of vibration, ice. The picture is one of descending vibrations. In a similar vein, as we peer into the interior of a human cell, we find smaller and smaller constituents.
Light appears as either a particle or as a wave.
Our descendant journey is the complementary opposite of the ascent. When we descend deep into what is solid, we arrive at vibration again. Furthermore, everything radiates. Everything has electro-magnetic emanations that can now be measured. Think of consciousness as something that is wider in concept than the self-reflective consciousness of we human beings.
