Purpose

The purpose of this experiment is to explore light transmission through polarizing filters. We will measure the resistance of a photocell when exposed to polarized light, allowing us to calculate the intensity of light passing through various setups of polarizing filters. The physical principle underlying this experiment includes the application of Malus's law, which gives a quantitative description of how light intensity is affected by a polarizer.

Introduction

The experiment involves utilizing polarizing filters to observe the behavior of light as it passes through them. The principle of polarization involves the restriction of light waves to a single plane. When unpolarized light hits a polarizer, its intensity is halved. Malus's Law states that when polarized light passes through a second polarizer, the intensity (I) after the second filter can be calculated using the equation: I = I0 * cos²(θ), where I0 is the intensity of the light before entering the polarizer and θ is the angle between the light polarization direction and the axis of the polarizer. In this report, both theoretical relationships and experimental data will be closely analyzed to observe the effects of different filter orientations on light transmission.

Procedure

The experimental setup was conducted in a dimly lit room to ensure that external light sources did not affect the readings. A digital multimeter was used to measure the resistance of a photocell positioned at various distances from a flashlight, with resistance values recorded for different polarizer orientations. The step-by-step procedures included assembling the equipment, adjusting the polarizers to specific angles, measuring resistance values, calculating intensity, and plotting the results in graphical form. Each step was executed precisely to maintain the integrity of the data collected.

Data, Calculations, and Questions

All pertinent data abided by scientific practices. The data tables recorded resistance values in ohms, demonstrating how they changed based on the configuration of the polarizers. The calculations applied unformatted resistance data into the selected equations, yielding intensity values subsequently plotted on graphical representations.

Results and Conclusion

The results indicated a consistent relation between the angle of the polarizing filters and the measured light intensity. For instance, when one polarizer was aligned at 0º, the measured intensity was highest at 40 W/m², and upon adjusting the second polarizer to 60º, intensity decreased as predicted by Malus's Law, illustrating a critical relationship between angle and intensity of polarized light transmission. The conclusions of this experiment reinforce the relevance of theoretical concepts in explaining observable phenomena in optics. The polarity of light, as experimentally verified, mirrors theoretical expectations, thus validating our approach and results.
