The pattern resulting from the superposition of two waves is often called interference. In this section we will look at the interference of two waves traveling in the same direction.

In a one-dimensional standing wave, the nodes were points along the medium where destructive interference occurred, and antinodes were points where constructive interference occurred.

This section explores the interference pattern produced by two sources. The example is shown in two dimensions, but the math also applies to the real three-dimensional world. To see what …

Consider wave interference in two dimensions when the waves have the same frequency (wavelength) and amplitude, and when they are vibrating at the same time (in phase).

Under these conditions, the points of constructive and destructive interference form a complex pattern, which we will refer to as an interference pattern. To begin the discussion, consider two …

1D vs. 2D Arrays As we’ve seen, a 1D antenna array enables control of the radiation in the direction of the array. For instance, an array of isotropic radiators arranged along the z-axis …

Put up a barrier to explore single-slit diffraction and double-slit interference. Experiment with diffraction through elliptical, rectangular, or irregular apertures. Make waves with a dripping …

•analyze two-point-source interference patterns in a ripple tank and in the interference of light (Young’s experiment) using diagrams •derive and apply equations relating the properties of …

When two waves are traveling in the same medium but in opposite directions, different interference patterns form. If the two waves moving in opposite directions have the same …

Mar 28, 2025 · The interference fringes run parallel to the x 2 axis, meaning the locations of the interference peaks and valleys depend on x 1 but not on x 2. In fact, if we measure particle 1, …
