A point in a wave pattern where the amplitude of the wave is zero, resulting from total destructive interference of two or more waves.
Boundary
A region or interface between two media with different properties, such as density or elasticity, where waves can be partially or totally reflected or transmitted.
Constructive interference
A phenomenon that occurs when two or more waves combine to create a wave of greater amplitude. This happens when the peaks and troughs of the waves align, resulting in a larger wave than either of the original waves.
No interference (destructive interference)
A phenomenon that occurs when two or more waves combine to create a wave of smaller amplitude. This happens when the peaks and troughs of the waves do not align, resulting in a wave that is smaller than either of the original waves.
