What is constructive interference?

Solution
If two waves reach a point in phase, so that crest of one wave falls on the crest of second and trough falls on the trough. Also, the amplitude of the resultant wave is scalar sum of the amplitude of two waves, then intensity of resultant wave at that point is maximum and constructive interference is said to take place.
