The Physics Behind How Your Microwave Heats Food

~60 min · 15 stations

The Physics Behind How Your Microwave Heats Food is a self-paced learning path in Physics & Quantum Mechanics, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify electromagnetic spectrum properties; explain water molecule dipole structure; trace microwave oven development milestones.
