I'll assume that you mean "what is the frequency in cycles per second of a common microwave oven"?
Roughly, the number is about 2.45 giga-cycles per second, or giga-Hertz (GHz). That's 2450 million cycles per second. This is not on continuously. Burst of the frequency are used to cook food with gaps between them to allow the heat to propagate through the food.
Or is that "what is the frequency in cycles per second of the portion of the electromagnetic spectrum called 'microwave'"?
"Microwaves" are defined as those with wavelength between 1 meter and 1 millimeter, or frequencies between 300 megahertz and 300 gigahertz. That's 300 million to 300,000 million (or 300 billion) cycles per second.
So the operating frequency of a microwave oven lies within the range of "microwaves".
Microwave is an electro-magnetic wave and travel at speed of light or 3x108 m/s.
The speed of a microwave is approximately 299,792,458 meters per second, which is the speed of light in a vacuum. The frequency of 3 GHz refers to the number of oscillations per second, not the speed of the microwave itself.
The radiation used in the microwave oven to cook turkeys in 10 seconds has a frequency of 2,450,000,000 Hz (2.45 GHz). In the communications world, the label (microwave) is attached to signals in the range of 3,000,000,000 Hz to 300,000,000,000 Hz (3 - 300 GHz).
The speed of a microwave in air is approximately 300,000 kilometers per second, which is the speed of light in a vacuum. When passing through other materials, such as air, the speed of a microwave will slow down slightly due to the material's density and composition.
1 foot per second = 0.3048 meters per second.
0.000300405757 mph per second.
The frequency can range between 300 MHz and 300 GHz.
It equals 9.67 metes per second.
.10 meters per a second equals 10 meters per a second
420 gallons per second is about 1,589.7 liters per second.
100 megabits per second (Mbps) = 12800 kilobytes per second (KBps)
2 MB per second equals 16,777,215.9 bits per second.
