What is the frequency of the microwaves in a microwave oven? The wavelength is 12 cm.
I have to give the answer in GHz
To determine the frequency of the microwaves in a microwave oven, we can use the formula:
Speed of light = Frequency x Wavelength
The speed of light in a vacuum is approximately 3 x 10^8 meters per second (m/s).
First, let's convert the wavelength from centimeters (cm) to meters (m):
12 cm = 12/100 m = 0.12 m
Now we can rearrange the formula to solve for frequency:
Frequency = Speed of light / Wavelength
Frequency = 3 x 10^8 m/s / 0.12 m
Frequency = 2.5 x 10^9 Hz
Since 1 Hz is equal to 1 cycle per second, we can convert the frequency to gigahertz (GHz) by dividing it by 10^9:
Frequency in GHz = 2.5 x 10^9 Hz / 10^9
Frequency in GHz = 2.5 GHz
So, the frequency of the microwaves in a microwave oven with a wavelength of 12 cm is approximately 2.5 GHz.
