Final answer:Thefrequencyof a microwave oven with a wavelength of 12.24 cm is 2.45 × 10⁹ Hz.Explanation:The frequency ofelectromagnetic radiationcan be calculated using the formula v = λf, where v is the speed of light, λ is the wavelength, and f is the frequency. In the case of a microwave oven with a wavelength of 12.24 cm, we can calculate the frequency as follows:v = 3.00 × 10⁸ m/s (speed of light)λ = 12.24 cm = 0.1224 mSubstituting these values into the formula:3.00 × 10⁸ m/s = 0.1224 m × fSolving for f:f = (3.00 × 10⁸ m/s) / (0.1224 m) = 2.45 × 10⁹ HzTherefore, the frequency of a microwave oven with a wavelength of 12.24 cm is 2.45 × 10⁹ Hz.Learn more about Frequency of electromagnetic radiation here:brainly.com/question/7596563#SPJ6...
