Radio waves at the frequency of 2,450 MHz,
often inaccurately referred to as "microwaves".
Infrared waves from the electromagnetic spectrum are used in heat lamps and heat sensing devices.
Most commonly, X-Rays.
Electrical converted to electromagnetic waves.
The common name for electromagnetic waves is just that: "electromagnetic waves". There is no other commonly used term. Specific parts of the spectrum have common names, for example light (or visible light), radio waves, x-rays, etc. - but none of this means exactly the same as "electromagnetic waves". Visible light, for instance, is just one type (or frequency range) of electromagnetic waves.
In a microwave oven, we find that microwave energy (from the microwave portion of the electromagnetic spectrum) are used. In a conventional oven, gas or electricity is used to create infrared heat, so we find infrared radiation (from the infrared portion of the electromagnetic spectrum, which is just below the visible light or optical portion) used there. If the oven happens to be a combination microwave and conventional, we'll find both types of electromagnetic waves generated for use inside.

Popcorn oil is generally used for helping pop popcorn. There are different types of popcorn oils, such as coconut oil, soybean oil, canola oil, corn oil, and sunflower oil.
Radio Frequency
So is the "heat" radiant heat, an electromagnetic wave? (Heat is used to mean many things.) Electricity gets turned into the electromagnetic infrared (heat).
Most commonly, X-Rays.
Heat.
IrDa
Infrared. :)
Most likely yes. But why would you freeze popcorn in the first place? You may find that when frozen popcorn is put in a popcorn machine, the outside of the kernals will "cook" much quicker than the insides will heat up. This means that they kernals may end up burnt on the outside before the oil inside the kernal has reached a heat that will make it pop. This may result in burnt popcorn.
A Chemistry laboratory, to heat things.
