Explanation 1) Concept: If the original light is initially unpolarized, the transmitted intensity is half of the original intensity. If the original light is initially polarized, then the transmitted intensity depends on the angle between the polarization direction of the original light and the polarizing direction of the sheet and the intensity is given by the equation 33 - 38 . Using this, we can calculate the fraction of the initial light intensity that emerges from the system. 2) Formula: I = I 0 cos 2 ⁡ θ 3) Given: i) θ 1 = 20 ° ii) θ 2 = 40 ° θ 4) Calculations: If the original light is initially unpolarized, the transmitted intensity is I = I 0 2 As the original light is initially unpolarized here, I 1 = 1 2 I 0 If the original light is initially polarized, then the transmitted intensity is I = I 0 cos 2 ⁡ θ So, the intensity from the second sheet is I 2 = I 1 cos 2 ⁡ θ 1 ′ And the intensity from the third sheet is I 3 = I 2 cos 2 ⁡ θ 2 ′ So, I 3 = I 1 cos 2 ⁡ θ 1 ′ cos 2 ⁡ θ 2 ′ Thus, I 3 = I 0 2 cos 2 ⁡ θ 1 ′ cos 2 ⁡ θ 2 ′ … … … … … … … … … … … … … … … … … … … … … … ( 1 ) Where θ 1 is the relative angle between the first and the second polarizing sheet and the θ 2 is the relative angle between the second and the third polarizing sheet

Three slits, each separated from its neighbor by d = 0.06 mm, are illuminated by a coherent light source of wavelength 550 nm. The slits are extremely narrow. A screen is located L = 2.5 m from the slits. The intensity on the centerline is 0.05 W. Consider a location on the screen x = 1.72 cm from the centerline. a) Draw the phasors, according to the phasor model for the addition of harmonic waves, appropriate for this location. b) From the phasor diagram, calculate the intensity of light at this location.
