How To Measure The Speed Of Light With A Microwave Oven Complete Guide

Youll find your ovens frequency on a label affixed to the backside or inside the door. So if you have measured 6cm and your oven operates at 2450 MHz then your measured speed of light is 012 x 2450000000 294000000 metres per second. So then all you need to do is to melt cheese in a plate and with a simple ruler measure the distances between the first two areas in the cheese that start melting.

Look for a sticker on your microwave that tells you its frequency in Hertz Hz.

If c is what we wish to determine we will have to know the other two variables. C frequency of the light x wavelength. Ours is 2450 MHz. This may not be something youd thought of doing but now you know how the speed of light can be measured using only some marshmallows and a microwave ovenWa.
