For what values of $\delta x$ will the superposition of the two waves show total constructive interference? Below are several possible values of $\delta x$ in terms of the wavelength, $\lambda$. Select all that will lead to total constructive interference. $\delta x = 0$ $\delta x = \frac{\lambda}{4}$ $\delta x = \frac{\lambda}{2}$ $\delta x = \frac{3\lambda}{4}$ $\delta x = \lambda$ $\delta x = \frac{5\lambda}{4}$ $\delta x = \frac{3\lambda}{2}$ $\delta x = \frac{7\lambda}{4}$ $\delta x = 2\lambda$

Four independent waves are represented by the following equations: $X_{1}=a_{1} \sin \omega t \ldots(1) ; \quad X_{2}=a_{1} \sin 2 \omega t$ (2) $X_{3}=a_{1} \sin \omega_{1} l \ldots(3)$ and $X_{4}=a_{1} \sin (\omega t+\delta)$ (4) Interference is possible between waves represented by equations (a) 3 and 4 (b) 1 and 2 (c) 2 and 3 (d) 1 and 4
Two sources as in phase and emit waves with $\lambda=0.42 \mathrm{m}$. Determine whether constructive or destructive interference occurs at points whose distances from the two sources are (a) 0.84 and $0.42 \mathrm{m}$, (b) 0.21 and $0.42 \mathrm{m},$ (c) 1.26 and $0.42 \mathrm{m},$ (d) 1.87 and $1.45 \mathrm{m},$ (e) 0.63 and $0.84 \mathrm{m}$ and $(\mathrm{f}) 1.47$ and $1.26 \mathrm{m}$.
