Why Doesn't Fire Cast a Shadow?

Why does a candle flame illuminate an entire room but cast no shadow of its own? In this video, we dive deep into the fascinating optical physics, thermodynamics, and chemistry behind the true nature of fire. From why a flame is an invisible combustion process made visible only by glowing, microscopic soot particles to how turbulent hot air acts as a refractive lens, learn why light passes right through fire. Discover why flames drown out their own shadows, how invisible hydrogen flames work, and the exact experiment using salt and a sodium lamp that turns a flame jet black to cast a solid shadow. #Physics #ScienceExplained #Optics #FireScience #Chemistry #HowItWorks #Thermodynamics #PhysicsExperiment #Stem #ScienceFacts
