that the length of path BDE may be varied. If Dis pushed in so that the two paths BCE and BDE are the same length,the waves take the same time to travel by either path from B to E,and therefore the two sets always arrive in the same phase. Theywill therefore reinforce each other and produce… … Fig. 654. —Divided tube for producing interference. the other, and the two neutralising each other, silence results, andthe manometric flame ceases to be disturbed. On further with-drawing D, a point is reached for which the path BDE is one wave-length greater than BCE. The two waves are then in…
