Destructive interference occurs for path differences of one-half a wavelength. To answer these questions, consider the diagrams below. The pattern is characterized by a collection of nodes and antinodes that lie along nearly straight lines referred to as antinodal lines and nodal lines. Answers and Solutions What's Your Question? The difference in distance traveled by the two waves is one-half a wavelength; that is, the path difference is 0. Like this video? The wave from Source 2 S 2 travels a distance of 4 wavelengths to reach the same point. Construct a sketch of the physical situation and determine the wavelength of the waves. Watch Queue Queue.

  • If the distance traveled by the waves from two disturbance is same, then path difference will be zero. Once you know the path difference, you can find the phase. Visit BYJU'S to understand the relation between phase difference and path difference, also learn formulas, SI units and explained along with the diagram. Path difference: It is the difference between the lengths of two paths of the two different waves having same frequency and travelling at same velocity.

    A No Reviews. The wave from Source 2 S 2 travels a distance of 6 wavelengths to reach the same point. A point on the fourth nodal line is Add to. Stanford Recommended for you.

    Nodal Points:. The point is formed as a wave crest travels a distance of 3 wavelengths from point S 1 and meets with a second wave crest that travels a distance 4 wavelengths from S 2.

    Infact, cos wave is just the sine wave phase-shifted.

    Sign in. The wavelength is 4. The diagram below shows two waves traveling along different paths from different sources to the same point in such a way that a crest is meeting a crest. The difference in distance traveled by the two waves is one-half a wavelength; that is, the path difference is 0.

    1. Infact, cos wave is just the sine wave phase-shifted. Two waves traveling along different paths from different sources meet at the same point in such a way that a crest is meeting a crest; constructive interference occurs.

    2. A point on the fourth nodal line is The diagram below depicts the destructive interference of two waves from the sources.
