pair of in-phase waves results in formation of a single wave greater of amplitude than either of its components

pair of out-of-phase waves results in the formation of a single wave of lesser amplitude than at least one of its components

when waves of different frequencies interfere, waves are in-phase , while others are out-of-phase

when two out-of-phase waves are of equal amplitude

pair of in-phase waves results in formation of a single wave greater of amplitude than either of its components

their peaks(maximum value) & their troughs (minimum values) occur at the same time

their peaks(maximum value) & their troughs (minimum values) occur at different times

formation of a single wave of greater amplitude than either of its components

formation of a single wave of lesser amplitude than that at least one of its components

when there's two pairs of waves where their peaks & troughs occur at different times at equal amplitude

same direction

perpendicular
