This question is about the interference pattern observed when the waves from two microwave transmitters interfere.
The first parts of the question involve the wavelengths of microwaves being the same for each transmitter. For the last part the question proposes that the wavelength of one of the microwave transmitters is halved (from 30 mm to 15 mm). The question asks what observational effect this will have on the interference pattern.
Now at first glance I notice that since the wavelengths are not the same for both microwaves the two microwave sources have different frequencies and are therefore no longer coherent sources, and thus I would intuitively expect no interference pattern to occur. Am I correct? Or is there some new interference pattern that would form in this situation?
