What is a simple definition of microwave radiation?
microwave radiation is radiation that comes from microwaves
Why the microwave devices called as microwave devices?
The (electromagnetic ) radiation they emit is short or micro wavelength ( 2.45 GHz frequency) which causes resonance in water molecules, resulting in rapid heating.
What is dielectic heating?
Dielectric heating, also known as electronic heating, RF (radio frequency) heating, and high-frequencyheating, is the process in which a high-frequency alternating electric field, or radio wave or microwave electromagnetic radiation heats a dielectric material.
Does a microwave use light energy?
yes its does because when the microwave is on and the plate is rotating,the light is actually heating the food. It is not the visible light that does the heating, that is provided simply so you can see inside the oven. It is the microwaves that do the heating, by agitating molecules of water in the food. That's why you can't heat dry food in microwave oven. The microwaves are EM radiation like visible light, but a different wavelength.
Why Radio waves and microwaves are non ionizing radiation?
Because they don't have enough energy (or a short enough wavelength) to knock electrons off of atoms (ionization).
Is heating chicken in a microwave conduction?
No, it is thermal radiation.
What are some examples of radiation heating?
A light bulb, campfire and A Microwave Oven •
What are the advantages and disadvantages of microwave radiation for heating a room?
The advantages and disadvantages of microwave radiation is that it is extremely harmful to humans and living things in general however it is very useful.
Is there any radiation from the mobile tower which will affect the human lives?
Basically no. Microwave radiation only has the effect of heating things up (think of the microwave in your kitchen). There has been some debate whether this could heat up your brain and what effects it would have, but it has generally found to have little or no effect.

How a campfire and microwave are examples of heat transfer through radiation?
Standing next to a campfire you will be warmed by its radiant heat (IR radiation).However a microwave cooker generates heat by boiling water inside the food, then the steam heats the food by a combination of conduction and convection (not radiation). There is some trivial heating of the microwave cooker's walls by IR radiation from the hot food, but this is so trivial you will not be able to measure it and the steam from the food will still condense on the cold walls (which is transfer through convection and warm them more than the IR radiation did).Note: microwave radiation is NOT thermal radiation (IR radiation) and must be transformed to become heat.

Do microwave ovens use electromagnetic radiation?
Yes, microwave ovens use electromagnetic radiation.
What property of heat is a food cooked in a microwave oven?
microwave is an electromagnetic wave in order of micrometer (one thousandth of meter). Because every electromagnetic wave is a radiation, microwave is radiation. Therefore, microwave oven which utilize microwave is transferring the heat via radiation.
