I am very confused as to how diffraction even happens. I am thinking that radio transmitters are those tall towers. (My country doesn't have those, our lines are underground).
Where is the 2nd antenna, and how does the diagram look like?
Does it look like: (The dashes are to fill up space)
-------------Antenna 1
Source--------------------------Receiver 1km away
-------------Antenna 2
The question seems to suggest that the distance between the 2 antennas is the 'slit width', through which radio waves (from some other source) pass through and get diffracted.
However, I am thinking that the antenna is the source of radio waves, meaning that they are the 'slits' in a 2-slit interference setup, and thus any diffraction should be due to the 'slit width', which is inherent to each antenna, and not dependent on the 2nd antenna.
Am I wrong?
Also, because the question mentions some 'problem with signal strength due to diffraction', am I right to say that the problem is that of reduced intensity detected?
The answer to the question is E.
