[DOC File]TAP 321-2: Calculating the wavelength in two-slit interference
https://info.5y1.org/path-difference-and-phase-difference_1_5ca5a2.html
The path difference is half a wavelength, because if the waves first interfere destructively here, they must be out of phase and the smallest path difference which will do that is half a wavelength. 3. Sin is the ratio path difference / d of two sides of the right-angled triangle, where the path difference is the length of the opposite side and ...

Therefore, there is a net phase difference produced by the reflections. The path difference for these two rays is 2t, where t is the thickness of the film. The wavelength in the film is . Execute: (a) Since the reflection produces a net phase difference, destructive interference of the reflected light occurs when The minimum thickness is 96.4 ...

Phase and phase difference All points in one section between two consecutive nodes (or antinodes) are moving in phase. All points in the next section are 1800 out of phase with all points in this section. Thus, the only possible phase differences are 00 and 1800. All points within one wavelength have a different phase.

This phase difference is due to their path length difference. To display this path length difference, we find a point b on the second ray such that the distance from that point to the screen is the same as the path length for the first ray. Then the phase difference is the distance from b to the center of the slit.

For normal incidence, the path length difference between the two reflected waves is 2t, where t is the film thickness. A phase change of 180o is equivalent to the phase change that comes from a path length difference of one-half wavelength. Thus, in order for these two reflected waves to be in phase and interfere constructively, we must have,
