Microwave standing wave calculations (max/min Intensity, Wavelength)

AI Thread Summary
The discussion revolves around calculating the wavelength of microwaves using standing wave principles and interference patterns. Participants emphasize the importance of understanding path differences and the conditions for constructive and destructive interference, noting that reflections can introduce phase shifts. A key point is that the difference in distance between maxima and minima is related to the wavelength, specifically that it equals a quarter of the wavelength. Confusion arises regarding the interpretation of path differences and the order of maxima and minima, with suggestions to use symbols instead of numbers for clarity. The conversation highlights the complexity of wave interference and the necessity of careful calculations to determine wavelength accurately.

Would you be able to find the wavelength if all that was given to you were the first minimum at 8.4 cm? The answer is yes. Read post #28 for a hint. Each of the four given values for ##y## can be used to find the wavelength independently of the others. Figuring out how to do it will deepen your understanding of interference.
Yes I understand how you only require one as long as you know the order. Thanks for helpjng

i believe it is one wavelength due to the fact that the distance between adjacent maxima are one wavelength apart. Ive realsied ive only done from the transmitter to the reflector which is only half the distance so that is why i am off by a factor of two
Yes, you calculated just half of the path difference. This is why you got the wrong value for wavelength.
