Why does my microwave work?

Question

My microwave is metal inside, and has/came with a metal revolving tray. It's definately a microwave, and it's definately metal inside.

I was under the impression that metal shouldn't be put inside a microwave oven.

It's a sharp, jet convection and double grill 800w band D microwave.

Answer 1

I don't know what your microwave's made of.

What I do know is that it isn't made of a material which has energy band gaps with the same energy as the microwaves provide. Microwaves are tuned to give off a specific wavelength (around 12cm) that excites water easily.

A microwave normally causes sparks in a metal as electrons in the metal are excited (having absorbed the energy from a microwave). This happens because the energy of the microwaves are similar to the energy of the bandgap in the metal.

Answer 2

If you look at the top inside of the unit you will see an area which looks like shiny paper. This is where the microwaves enter the chamber.
The metal of the rest of the unit absorbs the waves rather than letting them outside of itself where they can cook your body quite effectively!
A guy in a fast food restaurant blocked the cutout which turns the unit off when you open the door. He died of microwaved kidneys.

Answer 3

yes I have one too I thinkits a man made metalic like subtance to withstain the convection ovens heat

Answer 4

It's not metal is the answer, it's an non-metallic alloy that imitates metal in look and feel.
