Just a small electronic beeper to signal when cooking is complete, a control key is pressed, etc.

How does food get crispy in the microwave?
Things like hot pockets and microwave pizzas use what is called a susceptor (usually in the form of a sleeve or container). These susceptors convert microwave energy into heat, which help crisp up food in the microwave, countering the effects of sogginess that is synonymous with microwave ovens. For more information: http://en.wikipedia.org/wiki/Susceptor
Sound energy as a carrier of energy?
Yes. Sound energy is a carrier of energy.
Is the interior light a necessity for a Panasonic microwave because your light is not on when your microwave is in use?
The purpose of the light in a microwave oven is to enable the user to observe the progress of the cooking, and to serve as another indication ... in addition to the sound of the fan ... of when the oven is energized. The light is only a convenience, and has no effect on the operation of the appliance.
What is Vibration of molecules energy called?
Gravitational Energy.
What has more energy a microwave signal or a gamma ray?
The photon (quantum) at gamma frequency has more energy than a photon at microwave frequency has. But you can easily generate a beam of microwaves carrying more energy than, for example, the gamma rays that enter your house from space. Just use a more powerful source of microwaves to generate more photons. No big deal. The one in your kitchen that you use to heat the leftover meatloaf pours out far more energy every second than gamma rays bring into your house, but each microwave photon carries much less energy than a gamma photon does.
What energy is wasted by a microwave?
Sound
Does a microwave use radiant energy?
Both microwave radio transmitters and microwave ovens generate and pour out radiant energy.
Does a microwave use heat energy?
Yes, microwave uses heat energy. It helps in cooking.
What kind of energy does a microwave oven use?
A microwave oven uses electrical energy (which is electromagnetic energy) from the mains, and it generates microwave energy (which is also electromagnetic energy) to heat/cook food items.
Is the Panasonic Energy Star approved?
No, this microwave is not energy star approved. In fact, Energy Star does not currently approve/label ANY microwave ovens. However, most microwave ovens of the same size/wattage use comparable amounts of energy, and microwave ovens use substantially less energy than conventional ovens.
Does a microwave use machanical energy?
because It moves
What energy transformation occurs in an oven?
The electricity (electromagnetic energy) that drives the microwave oven is routed to the magnetron, which generates the microwave energy. (The electricity and microwave energy are both forms of electromagnetic energy.) The microwaves travel through a waveguide into the cavity (the cooking space) in the oven, and used to excite chemical bonds in the food items. This is a conversion of microwave energy (electromagnetic energy) into the mechanical energy of heat.
Is there a light inside of the microwave when it is not in use?
No, when it is not in use, the microwave would not have a light on. Why would you want the light on when you are not using it and waste energy?
What energy transformation in a microwave?
The microwave undergoes a variety of energy transformations when you are heating food. Starting from electrical energy (obtained via the mains power point/wall socket), the energy is transformed into microwave/thermal radiation (electromagnetic radiation/energy). These 'microwaves' react with the water particles in the food and cause them to vibrate. The friction produced by these vibrations produces heat and ultimately cooks/heats up your food. However, there is some energy that is transformed into light (the light you see when the microwave is one), sound (that humming noise you hear when it's operating) and kinetic energy (the rotating disk inside the microwave). Energy is transformed from electrical to heat, sound and light (if the microwave has a light). Energy is transferred to the food via the process of convection.

Why does a microwave use less energy than a conventional oven?
Microwave takes less time to cook
