· recall
that, in general, waves are transmitted and reflected at an interface
between media
· explain how different media affect the transmission/reflection
of waves travelling from one medium to another

· explain qualitatively how the movement of a source of sound
or light relative to an
observer/detector gives rise to a shift in frequency (Doppler effect).
