For any electromagnetic wave, the wavelength depends on the frequency, but the
speed doesn't. They all have the same speed. It's 300 million meters per second,
regardless of the frequency.
The wavelength at 3 GHz is 10 centimeters.
3.0 GHz: λ = about 0.3278 feet.
3 ghz to 300ghz
Wavelength = (speed) divided by (frequency)= (3 x 108) / (3 x 109) = 0.1 meter = 10 centimeters
"Microwave" is an electromagnetic wave, and is part of the category of radio waves.A radio wave is "microwave" when its frequency is above 3 GHz (wavelength isless than 10 centimeters).Ironically, the "microwave oven" radiates the food with high power radio wavesat a frequency of 2.5 GHz, so technically, it doesn't use 'microwave' energy at all.
Frequency = speed / wavelength = 3 x 108/0.001 = 300 GHz . (rounded)Most folks would call that a "millimeter wave" or a "darnedshort microwave", not light. It's certainly not visible.
Frequency = (speed) / (wavelength), so it depends on the speed of the wave. If it's a light wave, then the frequency is (3 x 108) / (15 x 10-9) = 20,000,000 GHz. If it's a sound wave, then the frequency is (343) / (15 x 10-9) = 22.9 GHz.
3 ghz to 300ghz
Wavelength = (speed) divided by (frequency)= (3 x 108) / (3 x 109) = 0.1 meter = 10 centimeters
Wavelength = (speed of light) divided by (frequency) = (3 x 108) / (9.76 x 109) = 0.03074 meter
"Microwave" radiation is any radio wave at frequencies between 3 GHz and 300 GHz. Microwave cooking ovens are licensed to operate at a certain definite frequency, just like any other radio transmitter is. For microwave ovens in the US, the frequency is 2.450 GHz.
EM radiation with a wavelength of 15 cm has a frequency of 1.9987 GHz. (Giga Hertz) or close enough to 2GHz. Technically this is in the UHF (Ultra High Frequency) section of the radio spectrum which is 300MHz to 3GHz.

The formal definition of "microwave" is any frequency greater than 3 GHz. (Wavelength less than 10 centimeters.) Frequency bands allocated for microwave radio communication in the US are found in the neighborhoods of 6, 11, 13, 18, 23, 24, 27, and 38 GHz. Note: It looks like the the formal definition of "microwave" doesn't include microwave ovens ... they operate at 2.45 GHz.
"Microwave" is the official label for radio between 3 GHz and 300 GHz. That frequency range corresponds to wavelengths from 1 millimeter to 10 centimeters.
For any wave,Frequency = (wave speed) / (wavelength)For your wave:Frequency = (3 x 10^8 meters per second) / (0.01 meter) = 3 x 10^10 per second = 30 GHz
