Interference
When two or more waves overlap each other
Superimposing of waves is when two or more waves travel through the same medium and intersect. The net displacement is the addition of the waves amplitude. If they are in phase they increase amplitude; out of phase, the amplitude decreases.
Normally, two waves do not combine to form a new wave. Two waves approaching from almost the same direction will slowly cross each other. At the point where the waves cross, they will briefly make one wave. Its height can be calculated by a formula which multiplies the height of each wave by a sine function and adds the results.
They typically form on steep beaches and tend to be more erosive.
They superpose. Energy of the waves are redistributed to form a resultant wave with amplitude given by the summation of individual wave's amplitude. If the two waves are of same frequency, speed and amplitude and travelling in opposite direction den stationary waves are form.
They form from the waves and thesand pressure so...when the waves get bigger the more shells!
