In gallery: Atmospheric optics Atmospheric refraction Inferior mirages (road)

This unique photo shows an erect image of the car below the car, due to the curvature of the road. Both the first-order and second-order inferior mirages are visible, as a wet spot on the road. The second-order reflection again inverted the first-order reflection, creating an inverted image of the inverted image of the car, and thus an upright image. Note the sharpness of the second-order mirage.
