MJ18 P23 Q5 Microwave Interference and Source Phase Change | AS Superposition | CAIE A Level Physics

9702/23/M/J/18: (a) State the relationship between the intensity and the amplitude of a wave. (b) Microwaves of the same amplitude and wavelength are emitted in phase from two sources P
and Q. The sources are arranged as shown in Fig. 5.1.
A microwave detector is moved along a path that is parallel to the line joining P and Q. A series
of intensity maxima and intensity minima are detected. When the detector is at a point X, the distance PX is 1.840 m and the distance QX is 2.020 m. The microwaves have a wavelength of 6.0 cm.
(i) Calculate the frequency of the microwaves.
(ii) Describe and explain the intensity of the microwaves detected at X.
(iii) Describe the effect on the interference pattern along the path of the detector due to each
of the following separate changes.
1. The wavelength of the microwaves decreases.
2. The phase difference between the microwaves emitted from the sources changes to 180°.

Worse thing about finishing a levels is that I won’t be watching ur videos all day. I love u guys sm and the help that you have given to the students is literally such a big blessing. I will always remember you guys after graduating and I hope that we can meet one day so I can tell u all in person how much u have helped me, I cannot imagine passing physics if it wasn’t for u all. You guys have been there with me at 3am making me laugh with all ur sarcastic jokes that rlly made me feel less stressed and less scared of physics. In exchange of all the hard work u guys put in these videos I will remember you guys in my prayers and hope that u stay happy forever. ❤❤❤❤

hello fellow m/j 24 candidates, I see we've found our way here

Can you please solve recent Astrophysics related questions for A2 students?

[@machacooling]

Here at 6:09 ...When both the phase difference and path difference are whole numbers, the microwave detector at point X shows maximum intensity. But if one of them wasn't a whole number and caused destructive interference, what would the microwave detector show then??
