Question

An incident pulse reaches the boundary with a different medium. At the boundary, there is some reflection and transmission. The transmitted pulse is observed to be traveling slower than the original incident pulse.

 

One would expect the transmitted pulse to: a) invert b) not invert

One would expect the reflected pulse to: a) invert b) not invert

reflected pulse is INVERTED

transmitted pulse is NOT INVERTED
