True or false
1. When two pulses meet up with each other while moving through the same medium, they have a tendency to bounce off each other and return back to their origin.
2. Constructive interference occurs when a crest meets up with another crest at a given location along the medium.
3. Destructive interference occurs when a pulse with an amplitude of +5 units interferes with an amplitude of -5 units

1. False — pulses do not "bounce off" each other in a linear medium; they superpose while overlapping and then continue on their way unchanged (except for any loss/dispersion from the medium).

2. True — constructive interference occurs when crests meet crests (or troughs meet troughs), producing a larger amplitude.

3. True — a +5 and a −5 pulse sum to zero at the point of overlap, giving complete (destructive) interference.
