My son came home from baseball practice the other day and announced he was starving. My wife was out on errands and being the good mother that she was, she made sandwiches for us boys and left it in the refrigerator. I told my son about it and asked him to pop them into the microwave so I can join him.
I then heard the TV switched on and a few moments later the familiar humming of the microwave. I finished with my office reports and joined him in the kitchen. Kids have this habit of catching you off guard with questions that you’ve never even considered before. Dad, he said. What do a microwave and a TV have in common? Good thing science was my favorite subject in school and I said waveguides. I explained to him what microwave technology is all about and how it transmits electromagnetic energy from one place to another.
I also told him about other types of waveguides like double ridged waveguide and rectangular waveguides. He was clearly fascinated with the idea that he asked me to help him do a science project. I said of course and we proceeded to buy online the waveguides we needed.
