used to make images of individual atoms?6 You know how a microwave gets some parts of your food hot,but leaves other parts cold? Suppose someone is trying to convinceyou of the following explanation for this fact: The microwaves insidethe oven form a stationary wave pattern, like the vibrations of aclothesline or a guitar string. The food is heated unevenly becausethe wave crests are a certain distance apart, and the parts of the foodthat get heated the most are the ones where there’s a crest in the wavepattern. Use the wavelength scale in figure z on page 129 as a way ofchecking numerically whether this is a reasonable explanation.7 This book begins and ends with the topic of light.
