In a Young's double slit experiment, three polarizers are kept as shown in the figure. The transmission axes of P_1 and P_2 are orthogonal to each other. The polarizer P_3 covers both the slits with its transmission axis at 45^{\circ} to those of P_1 and P_2. An unpolarized light of wavelength \lambda and intensity I_0, is incident on P_1 and P_2. The intensity at a point after P_3 where the path difference between the light waves from s_1, and s_2 is \frac{\lambda}{3}, is [24 Jan 2025 Shift 2]

In a Young's double slit experiment, three polarizers are kept as shown in the figure. The transmission axes of P1 and P2 are orthogonal to each other. The polarizer P3 covers both the slits with its transmission axis at 45∘ to those of P1 and P2. An unpolarized light of wavelength λ and intensity I0, is incident on P1 and P2. The intensity at a point after P3 where the path difference between the light waves from s1, and s2 is ‌
