Heat waves don’t have shadows. Air has a shadow. When you’re seeing the shadows of “heat waves,” what your actually seeing is the shadows of the air at different densities as the heat moves through it. Kind of like how you can’t see sound, but if I stretch a bedsheet in front of a large speaker and play something with a lot of bass, you’d see the ripples across the sheet.
