Like the title says: when you see “heat rising” (the wavy/blurry area above a heat source), what are you actually seeing?
Bonus question: How does that cast a shadow? I noticed when I was opening my air fryer, I could see the shadow of the heat rising but, looking at the hot basket itself, couldn’t see it.
“wavefront of light”, “distorted from planar” 🤯
You took me straight back to a D- in intro to optics and modern physics where my classmates were trying to solve problems based on concepts, where I was trying to solve the problem of not understanding the concepts.
