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 170 MHz. One microwave generator is set to emit microwaves with a wavelength of 1.370 cm. If the second generator emits the longer wavelength, what is that wavelength?
