Question

A phase difference π between two interfering beams is equivalent to the path difference​

Answer 1

Answer:

Phase difference is related to quantum mechanics. If path difference b/w 2 waves is integral multiple of wavelength, which satisfies condition for constructive interference. ... sine wave is zero at the origin, but cos wave is not zero at the origin, its zero at pi/2. So the phase difference is pi/2.

Answer 2

π between two interfering beams:

Explanation:

• The way distinction between two meddling waves at a point on the screen is λ/6.
• The proportion of force at the point and that the focal brilliant periphery will be (Assume that inside because of each cut in same).

• Stage distinction is connected with quantum mechanics.
• If way contrast π waves is vital various of frequency, which fulfills condition for productive obstruction.
• sine wave is zero at the beginning, yet cos wave isn't zero at the beginning, its zero at pi/2. So the stage contrast is pi/2
