Consider an experimental setup where three equally spaced and equal-intensity coherent sources of green light (L₁, L₂, and L₃) are placed in a line. Using the phasor method and phase difference $𝛿=\frac{2\pi dsin\theta}{\lambda}$, determine the relative intensity $I/I_0$ of the light at point S.

In an experimental setup, three equally spaced and equal-intensity coherent sources of red light: L₁, L₂, and L₃ are placed in a line. Using the phasor method and phase difference of $\delta$ = $\frac{2\pi\cdot d\cdot\sin\left(\theta\right)}{\lambda}$, determine the locations of the maxima "θ_max" in the interference pattern.
