A constructive wave id when two crests from opposite directions converge and the end result wave is the sum of the two crests.
A destructive wave is when a crest and a troph from opposite directions converge. the end result wave usually cancels out (no wave) or they act against each other.
How do noise-cancelling headphones use wave interference to eliminate unwanted sound?
A : The music going into the ear acts as a constructive wave. Another wave is created through the headphones that acts as the troph with the same amplitude, and the background noise acts as the crest that creates a destructive wave that cancels out any noise.
Pulse wave: A pulse wave is a non-repeating wave; single disturbance.
Periodic : Periodic waves are waves that repeat at regular intervals. they require regularly repeating disturbances in order to be considered a periodic wave.
Longitudinal: A longitudinal wave is when several turns of the spring are compressed and released. The disturbance is in the same direction as the direction of travel. This wave occurs lengthwise.
Transverse: This wave occurs sideways. The spring is pulled sideways at a 90 degree angle (right angle) then released. The wave will travel across instead of lengthwise.
