au/micwave1.htm (21. veebruar 2008) 24 MICROWAVE OVENS. SUMMARY. I have chosen this topic for my work because it has found a lot of reverberation in media lately. Although media is more concerned about the health aspects, I have chosen to examine the construction and the work principle of the microwave ovens. I was interested in myths telling stories about the behavior of metals and eggs in the microwaves. The aim of my work is to give an overview about history of microwaves and explain the principles of its work and explain some reactions with different materials by carrying out some experiments. The most important component parts are magnetron, transformer, cooking chamber and the rotating plate, which assures the even cooking of the food. Cooking procedure can only be taken place when food contains dipoles, which rotate themselves under the influence of microwaves.
Let's face it you're a robot! Technology to millennials is different from what any other generation has seen it as. We don't like to list microwaves, radiators or anything like that as a part of it. The world of technology has grown so fat these couple of year that we don't consider a regrigirator to be more than a basic need. Even radios and televisions are starting to fall into that category of regular appliances every household has to have. Generation Y has a whole new list of technology which nowadays includes a phone, a computer, gaming consoles, a televison, and basically
