If you stand near a hot toaster why can you feel the heat?
you feel the heat because electromagnetic waves carry energy so objects that absorb electromagnetic radiation receive energy.
What ind of waves does a toaster produces?
A toaster produces waves of electromagnetic radiation. The wavelength of these waves is similar to the wavelength of red light, hence why the wires in toasters glow red. As we heat up the wire, electrons are exited to a higher energy level, when they come back down an energy level, they produce a quanta of energy, a photon. ie a particle of light :)
When you turn on a toaster what happens to the electrical energy?
The electrical energy gets transformed into electromagnetic (light) energy and thermal (heat) energy.
Do microwaves or xrays have a higher frequency?
Yes and no, but the answer is more complicated. The energy given off by the heating elements of both a toaster and microwave is electromagnetic energy. A microwave oven is a tuned source of radiation, commonly about 2.45 gigahertz with a wavelength of about 5 inches or a dozen centimeters. A toaster oven puts our radiant energy due to heating of the elements and that is a very broad source of electromagnetic energy. In the most common situation of a household toaster, the energy output is significant in the microwave and infrared (roughly millimeter to meter wavelength). Thus, the heating element of a toaster gives off energy that is both higher and lower in frequency than a microwave. The heating process of a toaster has a significant component that involves the temperature of the air which is increased when the internal surfaces of the toaster absorb the electromagnetic energy. The heating process of a toaster may be more or less a consequence of the heating of the air based on the design of the toaster. A bread toaster is different than a toaster oven in this regard. Finally, it is fair to say that the toaster puts out a significant fraction of its energy infrared part of the spectrum and that part of the toaster's output has a higher frequency than the microwave.
The energy produced by elctromagnetic waves?
Electromagnetic waves carry energy from place to place, but they don't produce it. You have to produce the energy that you want them to carry.
What energy does a toaster produce?
heat energy
When you turn the toaster on what happens to the energy?
The electrical energy gets transformed into electromagnetic (light) energy and thermal (heat) energy.
Does walking produce electromagnetic energy?
Walking produces motion, not electromagnetic energy.

What type of energy does a toaster produce?
It uses electrical energy to make thermal energy.

Is it possible for a toaster to convert light energy to heat energy if not what energy would it convert?
A toaster takes in electricity from some power source, then it uses this electricity to heat coils within the toaster. The coils get very hot, and emit heat in the form of electromagnetic radiation (light). The bread/bagel/sock that you put into the toaster absorbs this radiation and gets hot.
What is the physics of a toaster?
Physics is simply the study of the properties of matter and energy. The physics behind a toaster is that the toaster conducts electricity to produce heat, toasting bread or whatever other food.
