32. In contrast to the initial conditions of problem 30, we now consider waves W 2 and W 1 with an initial eFective phase diFerence (in wavelengths) equal to 1 2 , and seek positions of the sliver which cause the wave to constructively interfere (which corresponds to an integer-valued phase diFerence in wavelengths).

Unformatted text preview: Thus, the extra distance 2 L traveled by W 2 must amount to 1 2 λ , 3 2 λ , and so on. We may write this requirement succinctly as L = 2 m + 1 4 λ where m = 0 , 1 , 2 ,... ....
