Which type of interference occurs when two waves combine and the crests align with crests and the troughs align with troughs?

What is the phase difference between two waves that produce constructive interference?

What type of interference occurs when the crest of one wave meets the trough of another wave?

What is the path difference requirement for destructive interference to occur?

If two waves have a phase difference of 180°, what type of interference will occur when they combine?

What property of a wave determines if interference from superposed waves will be constructive or destructive?

Two waves having the same frequency combine with a phase difference of 90°. What type of interference will occur?

What type of interference occurs when two identical waves combine and produce a wave with double the amplitude?

Two waves combine with a path difference of 5 wavelengths. What type of interference will occur?

Two waves having wavelengths of 3 m combine with a path difference of 1.5 m. What type of interference will this produce?

Two waves combine with a phase difference of π radians. This will result in:

Two waves overlap while having a path length difference equal to 3λ/2. This will lead to:
