When two mechanical waves have a displacement in the same direction, and they overlap, what will the resulting wave look like and why?

the new wave will have the same displacement as the original waves due to constructive interference.
the new wave will have a smaller displacement than either of the original waves due to destructive interference.
the new wave will have a greater displacement than either of the original waves due to constructive interference.
the new wave will have the same displacement as the original waves due to destructive interference.

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
