How big are the microwaves that heat up food? The prefix micro suggests that the waves are small (think microscope or microchip). In fact, microwaves are a smaller variation of radio waves.
But compared to other EM waves, microwaves are pretty big. We can measure them in centimeters.
Take a look at how the size of microwaves compares with other types of EM waves. The diagram includes everyday objects to help us understand the scale of the wavelengths.
