Okay, so this question is pretty simple.
00:04
We just need to answer which of the radio waves is more easily diffracted around buildings, if it is the am or the fm radio wave.
00:16
But to answer this question, we must understand what is the am and the fm radio waves.
00:24
And the am is the amplitude modular radio waves.
00:29
And this is basically, we do not change the wavelength, but we change the amplitude.
00:36
So it's something like this.
00:38
We start with a small amplitude, and that's amplitude.
00:43
It's getting bigger and bigger, and we go back to the small amplitude again.
00:53
So the important thing about the am wave, the important thing about the am radio wave is that the wavelength never.
01:03
Change so all the time is lambda okay the only thing that changes the amplitude of the wavelength and what is the fm radio wave so the fm is the frequency modular so what that means is we do not change the amplitude but we change the frequency so we have patches of sorry let's do it again we have patches of high frequency and patches of low frequency...
