hello there I'm Irman, and I'm going to talk about the microwaves.
the movement of the microwave is a transverse wave. all of the transverse waves are moving into the object which is causing the food to heat up. Then when the second is up you take it out of the microwave and you're food is hot.
Microwaves are a very big thing for our lives because it helps us warm up food. If you don't want to cook it or bake the certain food you have you can just microwave it
Did you know that the microwave has many different amplitudes depending on the different amount of energy
lets say if you want a large amount of meat to heat up. You can make the micro have higher amplitude which will make it have more energy so it will heat up the food easier.
But let's say that you have a little amount of food and you only need a little amount of amplitude which will have less energy so it will not overheat the food but it will not leave the food cold
