Wave Interference. Interference occurs when two or more waves are at the same location at the same time. For example, the wind may create tiny ripples on top of larger waves in the ocean.The superposition principle states that the total vibration at any point is the sum of the vibrations produced by the individual waves.
If the path difference of two coherent waves is a whole number of wavelengths (n \lambda), constructive interference occurs. This occurs as the peaks and troughs of the waves line up and superposition occurs.
For each of the wave sets of picture below draw the resultant wave when the waves are superimposed in the middle section and the waves after they have interfered in the picture series on the right. Also label what type of interference as CONSTRUCTIVE or DESTRUCTIVE.
Figure 16.6.5: Destructive interference of two identical waves, one with a phase shift of 180° (π rad), produces zero amplitude, or complete cancellation. When linear waves interfere, the resultant wave is just the algebraic sum of the individual waves as stated in the principle of superposition.
Experiment with diffraction through elliptical, rectangular, or irregular apertures. Make waves with a dripping faucet, audio speaker, or laser! Add a second source to create an interference pattern.
Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the medium.
