A microwave is a form of electromagnetic radiation in the frequency range between 300 MHz (or 0.3 GHz) and 300 GHz. A microwave is also the "shorthand" name we give to a common appliance called a microwave oven. Are they the same?
Whether or not microwave ovens are the same as microwaves depends on the application of the term. Microwave ovens are called that because they contain a microwave generating device and direct the radiated electromagnetic energy (the microwaves themselves) into a cooking space (called a cavity) to heat drinks or food, or even to cook things.
Say an appliance salesman is saying to his/her junior helpers, "Arrange the microwaves on the shelves." This refers to the microwave ovens. It's not about electromagnetic energy called microwaves.
Take the case of an electronics teacher saying to his/her students, "The microwaves are reflected off the metal screen that is used in the construction of the dish." This does notrefer to microwave ovens, but the electromagnetic energy itself.

What are some examples of MicroWaves?
Two Examples of Microwaves are Microwave Ovens and RADAR (Radio Detection And Ranging).
Is there any radioactive material in microwave ovens?
There are no radioactive materials in microwave ovens: they use microwaves to cook food and heat liquids.
Why were the first microwave ovens referred to as radar ranges?
because microwaves both and radar systems both use microwaves
Why were the first microwave ovens sometimes referred to as radar ranges?
because microwaves both and radar systems both use microwaves
How do you use microwaves in eveyday life?
There's the obvious one: microwave ovens. Also, your cell phone relies on microwaves to communicate with the cell towers, wifi routers also pit out microwave signals.
Will food stored next to microwaves be contaminated?
No, microwave ovens are constructed in such a way that no 'microwaves' can escape the oven, so your food or anything else stored close by are safe.
What type of rays do cellphones and ovens use?
They use electromagnetic waves. cellphones use radio waves while electric and microwave ovens use infrared and/or microwaves
Why is light radio waves and microwave ovens related?
Light waves, radio waves, and microwaves are all on the electromagnetic spectrum.
Which microwave ovens are the most energy efficient?
All microwave ovens use only 1/3 to 1/2 the energy of a conventional oven or stove. Microwaves are not required to have an energy star lable to show you their average energy usage, But all the different wattages of microwaves are similar in average energy usage.
Can you open the door of a microwave oven when it is on?
Microwaves do not act like normal ovens unless you have a combination oven. True microwave ovens do not work with the door open and rely on friction between the molecules of water,sugar and fat to heat the food from within.
What waves do telephones use?
Mobile phones use microwaves - similar to those used in microwave ovens (but at much lower power !)
How does the wavelength of the waves used in microwaves ovens compare with the wavelength of waves used for radar?
Inches (microwave) vs. Feet (Radar).
