Inferior mirages bend light through hot, thin air near the ground
On blistering desert floors and asphalt, a layer of hot, less-dense air sits under cooler denser air. Light rays from the sky curve upward into your eye, painting a false “puddle” of sky on the ground.
That inferior mirage is refraction, not water — the brain reads bent blue light as a reflective surface ahead.
Heat edits vision. Mirages remind us that arid landscapes can rewrite the straight-line story light usually tells.
