Using the diagram,a. Compare (and contrast) how line A and line B are formed.b. On the diagram, draw in all the lines of constructive and destructive interference, and label all of the lines with their path length difference (ΔL) in terms of the wavelength (λ). **Wavefronts and Interference Pattern**1) The diagram illustrates wavefronts created by two coherent sources, \( S_1 \) and \( S_2 \), which are vibrating in phase.**Description of the Diagram:**- The diagram shows concentric circles around two point sources, \( S_1 \) and \( S_2 \), representing wavefronts.- Each circle signifies a crest of the wave, indicating the same phase point in the wave cycle.- The wavefronts emanate outward from both sources in a symmetrical pattern.- Lines marked as \( A \) and \( B \) indicate nodal and antinodal lines: - Line \( A \) is the central axis of symmetry where constructive interference occurs, with wave crests from both sources reinforcing each other. - Lines marked \( B \) represent points of destructive interference where troughs from one source meet crests from the other, resulting in cancellation.This pattern exemplifies the phenomenon of interference, a fundamental concept in wave physics, highlighting how coherent sources interact in space.

(a) In the given figure, line A is drawn by joining all the points of constructive interference, where either crests or troughs of both sources of the same order intersect. Line B is drawn by joining all the points of destructive interference, where crest due to one source intersect with trough of another source.(b) A crest and a trough together represents one wavelength.Path length difference ΔLA=7.5λ-7.5λ=0ΔLB=7.5λ-7λ=0.5λΔLC=7..5λ-6.5λ=λ
