HI there,
I have a thought question. Normally when we wish to warm up food in a microwave oven, common sense tells us that the lid of the plastic containter (or container of whatever material) should be off, so that the microwave can reach the food.
Just wondering...if the lid is on, ie the container is covered, can the food inside still be warmed? My guess is yes. My reasoning is that the microwave can pass through the material (ie. the material might be visually opqaue, but it allows microwaves through) and gain access to the food inside. My point is, a material might be opqaue to visible light, but at the same time, it is transparent to microwave. Of course, what determines whether the microwave can pass through the lid material is a matter of what the lid atoms do with the energies in the microwave (i.e. the electron energies level in the atoms).
Is my reasoning correct? (Sorry i can't try it out as i do not have a microwave oven)
