Imagine this scenario:
An aeroplane emits a sound wave. The sound wave propagates in all directions.
a) If the plane is flying forward, it emits a sound towards a reflector in front of it. When the sound is reflected, its frequency is reduced, presuming the plane is traveling towards the reflector
b)If the plane is flying in the other direction, it emits a sound towards a reflectorbehind it. When the sound is reflected, its frequency is increased, presuming the plane is traveling away from the reflector
Why are a) and b) as they are
