We're starting to put all the pieces together in terms of how one object can make so many sounds...and this means that the sound waves look very different! If we strike a tuning fork lighter or harder, this means that the vibrations will be bigger or smaller, changing the amplitude, or the wave's height.
If we pick a different tuning fork with a different frequency, we'll be changing the pitch. Higher pitched noises have a higher frequency (meaning more waves per one second of time). Lower pitched noises have a lower frequency (meaning less waves per one second of time).
This is starting to make sense...the car's speaker must be making all kinds of different vibrations (in terms of frequency and amplitude) that allow us to hear different sounds and make the window shake differently (or even not all all)!!!
