Part A 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 200 MHz. One microwave generator is set to emit microwaves with a wavelength of 1.440cm If the second generator emits the longer wavelength, what is that wavelength? Express your answer to four significant figures and include the appropriate units. HẢ ? A2 = Value Units
