You probably could tell that in
Movie 1 the horn was coming from inside the car that was being
driven. But, in Movie 2 the
horn was coming from an outside source...probably the truck that
was being driven by.
Intuitively
you were able to figure out where the horn noise was coming from
in each movie, but can you explain this
intuition?
Before
you answer that question watch two more movies, this time filmed
from outside a moving car. Again, try to determine where the horn
is coming from.
