Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.

Question

3.11
Two waves simultaneously present on a long string have a phase difference between them so that a standing wave
formed from their combination is described by
y(x,t) = 2Asin(kx + 2)cos(wt - 2)
(a) Despite the presence of the phase angle , is it still true that the nodes are one-half wavelength apart?
O Yes
O No
Explain.

Check Your Understanding The equations for the wavelengths and the frequencies of the modes of a wave produced on a string: n=2nLn=1,2,3,4,5...andn=nv2L=nf1n=1,2,3,4,5... were derived by considering a wave on a string where there were symmetric boundary conditions of a node at each end. These modes resulted from two sinusoidal waves with identical characteristics except they were moving in opposite directions, confined to a region L with nodes required at both ends.Will the same equations work if there were symmetric boundary conditions with antinodes at each end? What would the normal modes look like for a medium that was free to oscillate on each end? Don’t worry for now if you cannot imagine such a medium, just consider two sinusoidal wave functions in a region of length L, with antinodes on each end.
