Question

Two microwave signals of nearly equal wavelengths can generate a beat frequency if both are directed onto the same microwave detector. In an experiment, the beat frequency is 190 MHz. One microwave generator is set to emit microwaves with a wavelength of 1.220 cm. Part A If the second generator emits the longer wavelength, what is that wavelength? Express your answer with the appropriate units. $\lambda_2 = 1.333 \cdot 10^{11}$ m

Step 1

220 cm, we convert it to meters by dividing by 100: 1.220 cm = 0.01220 m The speed of light is approximately 3.00 x 10^8 m/s Frequency of the first microwave signal = 3.00 x 10^8 / 0.01220 = 2.459 x 10^10 Hz = 24.59 GHz Show more…
