I'm just curious. Why is it that we use microwave ovens to cook food and not some other wave of the EM spectrum?

You mentioned that if the microwaves leaked out, it could kill us. But I wonder, if it could harm us, how is it safe for our food? I see some people sometimes place a sheet of white tissue paper over their food before heating it up. Why do they do this?
triden said:I assume what he means is that the EM waves can cause gene and cell mutations in living creatures.
As for your last question, people put a paper towel over the food to keep the food from splattering all over the microwave. Things sometimes "explode" in a microwave. For example, a Twinkie explodes in 45 seconds (according to the manufacturer).
Why pi bonds and lone pairs, as opposed to other kinds.ShawnD said:Usually it isn't that violent as anybody that has used a microwave knows, sometimes a few drops of sauces splatter on the walls from escaping air.
UV mainly applies to things with pi bonds and lone pairs; that would be things like sugars, fats, and proteins.

ShawnD said:You can even test this by trying to heat water inside of a steel cup.

Microwaves are a type of electromagnetic radiation with a wavelength between 1 millimeter and 1 meter. They are commonly used in household appliances such as microwave ovens, as well as in communication and radar technology.
Microwaves work by emitting high-frequency electromagnetic waves that cause water molecules to vibrate and generate heat. This heat is what cooks or heats up food in a microwave oven.
Microwaves are used in cooking because they are able to heat food quickly and evenly. They also require less energy compared to traditional cooking methods, making them more energy-efficient.
Some advantages of using microwaves include faster cooking times, more even heating, and energy efficiency. They also do not produce a lot of heat, making them safer to use compared to stovetops or ovens.
While microwaves are generally safe to use, there are some potential risks associated with them. These include the possibility of burns from steam or hot containers, and the potential for uneven heating which can result in cold spots in food.
