The standard microwave oven uses only a tiny portion of the electromagnetic spectrum that is centered on 2.45 GHz. That's 2.45 gigaHertz or 2,450,000,000 Hertz (cycles per second). Almost all of the energy the unit generates is right at that frequency.

How does a microwave use waves?

A microwave oven uses electromagnetic waves to heat food by causing water molecules in the food to vibrate and generate heat from friction. These waves are produced by a device called a magnetron and are contained within the microwave oven cavity to effectively heat the food placed inside.


How can you use a microwave oven as a oven?

You can't. Only if it's a microwave-oven


What is the possible reason for degradation of wireless communication when microwave is in used?

Wireless communication is usually a form of radio communication. Radio communication uses a part of the electro-magnetic spectrum of radiation. Microwave ovens also use electro-magnetic radiation. If you have a radio that's operating close to the microwave range, or maybe an microwave oven that has a wide spectrum, then the oven can interfere with the radio.


What is the use of microwave oven?

The use of a microwave oven is to cook food or heat it quickly and efficiently using radiation.

Can you use aluminium vessel in microwave oven?

It is not recommended to use aluminium vessels in a microwave oven as it can cause sparks, arcing, and potentially damage the microwave. It is safer to use microwave-safe containers made of glass, ceramic, or microwave-safe plastics.


What part of the electromagnetic spectrum is used in ovens?

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.


Which is safer a microwave or an oven?

An oven as it does not use radiation to cook food.


What is combi1 meaning in microwave oven?

Your microwave oven has "combination" features, most likely a combination of microwave and convection cooking. Consult the user manual for your specific oven to find out how to use these features.


Can you use microwave with metal skewer in potato?

In a gas oven, yes. But NOT in a microwave.


Can I use aluminium dishes in microwave oven?

No, it is not safe to use aluminum dishes in a microwave oven. Aluminum can reflect the microwaves and cause sparks, potentially damaging the oven or even causing a fire. It is recommended to use microwave-safe materials such as glass or ceramic.
