Answer to Question 1

If at the instant two pulses overlap, they produce a resultant displacement that is greater than the displacement of either separate pulse, the result is constructive interference. If at the instant two pulses overlap, they produce a resultant displacement that is less than the displacement of either separate pulse, the result is destructive interference.
