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.
Great explanation! The anology of the pool was helpful!
“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.
