Final answer:
The wavelength of the microwave radiation emitted by a microwave oven at a frequency of 2.45x10⁹ Hz is approximately 0.122 meters, calculated using the formula for the speed of light divided by the frequency.
Step-by-step explanation:
To determine the wavelength of the microwave radiation emitted by a microwave oven with a frequency of 2.45x10⁹ Hz, we can use the formula for the speed of electromagnetic waves, which is c = λf, where c is the speed of light (approximately 3x10⁸ m/s), λ is the wavelength, and f is the frequency. We can rearrange this formula to solve for wavelength: λ = c/f.
Substituting the given values, we get λ = (3x10⁸ m/s) / (2.45x10⁹ Hz), which equals approximately 0.122 meters. Therefore, the wavelength of the microwave radiation is about 0.122 meters.
As a secondary note, the information provided indicates that microwave ovens produce radiation that causes polar molecules, like water, to rotate faster, thus heating up food.
