Can Cheese Measure a Microwave?

Description

Visualizing standing waves and estimating the speed of light It includes learning objectives, prediction and variables, a teacher-led procedure, hot-spot measurement table, λ ≈ 2d and c = fλ calculations, analysis questions, a worked example, teacher answers, uncertainty/evaluation, and an explanation of why the microwave tray rotates. Because this activity involves a microwave oven, I structured it specifically as a teacher-led demonstration with prominent safety guidance rather than an unsupervised student experiment.
