### Chem Homework Question Number 1.9

On number 1.9, in the 6th edition book, the wavelength of the third type of radiation solves to be 1 meter. Looking at an electromagnetic chart, 1 meter is the approximate wavelength of radio waves (or relatively close to that value). However, on the answer key, the radiation event is supposedly "microwave popcorn." A microwave typically has a wavelength of less than 1 according to the chart I am looking at. Is this an error in the textbook key or am I overlooking/misinterpreting something?

I have the 7th edition and the chart on Table 1A.1 says that a 1m wavelength is both microwave and radio wave
