How Does the Angle Between Two Polarizing Sheets Affect Light Intensity?

Click For Summary
To determine the angle between two polarizing sheets that results in transmitted light being one-third of the incident intensity, one must apply Malus's Law. Unpolarized light passing through the first polarizing sheet is reduced to half its intensity. The second sheet, oriented at an angle θ to the first, further modifies the intensity based on the cosine squared of that angle. The equation I = I0 * cos²(θ) can be used, where I0 is the intensity after the first sheet. Setting up the equation to find θ when the final intensity is one-third of the original intensity leads to solving for the angle that satisfies this condition. The discussion emphasizes the importance of showing work in the homework section for clarity and understanding.

Polarization physcs sum?

Unpolarized light is incident on 2 polarizng sheets placed on top of the other...each sheet reduces the intensity of unpolarized light by 50%..wat must be the angle between the characteristic direction of sheet such tat the intnsty of transmittd light is 1/3rd of the incident?
