Polarization of light refers to the process by which electromagnetic waves oscillate in a single plane. This phenomenon can be observed in a variety of different materials, including crystals, liquids, and gases. In this lab report, we will discuss the results of an experiment designed to investigate the polarization of light using a polarizer and an analyzer.
To begin the experiment, we first set up a light source, such as a lamp or laser, and positioned it so that it shone through a polarizing filter, or polarizer. This polarizer is a transparent material that only allows light waves oscillating in a specific plane to pass through it. We then placed an analyzer, which is another polarizer, in front of the light source. The analyzer can be rotated to different angles, allowing us to investigate how the polarization of the light changes as the angle between the polarizer and the analyzer changes.
As we rotated the analyzer, we observed that the intensity of the light passing through the analyzer varied. When the polarizer and analyzer were aligned, the intensity of the light was at its maximum. As we rotated the analyzer away from this alignment, the intensity of the light decreased. This is because the analyzer is only able to pass light waves oscillating in the same plane as the polarizer, and as the angle between the two increases, fewer and fewer light waves are able to pass through the analyzer.
We also observed that when the angle between the polarizer and the analyzer was 90 degrees, the intensity of the light was at its minimum. This is because at this angle, the polarizer and analyzer are perpendicular to one another, meaning that no light waves are able to pass through the analyzer.
In conclusion, our experiment demonstrated that the polarization of light can be controlled and manipulated using polarizers. By aligning or misaligning the polarizer and the analyzer, we were able to vary the intensity of the light passing through the system. This experiment provides a useful illustration of the principles of polarization and has a wide range of practical applications, including in sunglasses, LCD screens, and scientific instruments.

If a second filter is set-up in front of the first filter, the angle between the axis of one filter and the axis of the other will determine the intensity of the light passing through the second filter; if both axes are perpendicular to one another, no light will pass through; if the axes are parallel to one another, all of the polarized light will pass. The Fresnel lens is not just one lens but a number of prisms. In un-polarized light, electric field of light continuously changes its electric field. But we always can resolve E-field into its horizontal and vertical components. The light that exits the filter is said to be polarized , because the electric field vector points in a direction 1 P a g e parallel to the filter axis. It still could have, on the other hand, resulted in a minor discrepancy in the results. Next noticing how the best glare reduction is achieved from a filter with its transmission axis in a vertical position the light reflected from a horizontal surface is horizontally polarized.

Then with two filters were put together and aligned so that light passed through them, looking through them at a 1 page, 252 words Shades Dear Mom, This past week i endeavored on the delightful effect of polarized light. The analyser was rotated from β to the point at which the light is no longer visible and the location on the analyser where this occurs was recorded. Adhere to grammar, spelling and punctuation criteria. Henceforth, the location of the magnetic and electric fields in the transverse wave can be identified and cancelled out. PART II- In part two of the experiment one polarizing filter was placed on top of the other so that light was transmitted. Also, as mentioned in the experimental procedure, the polariser is not one hundred percent efficient. Then holding each of the two linear polarizing filters in front of the eyes in a way that best reduces the glare from the window.

Such light is called randomly polarized or un-polarized. Try to develop your own. Phys 1402 — L Names: Josephine Do, Hunter Virkus, Fernando Hernandez, Paola Lujan, Katelynn Gonzalez Procedure This lab is an exercise in creating your own complete lab report. Keeping the table positioned at the point where this occurs, the telescope crosshairs can be centred on the light and a reading from the vernier scale is taken. In conclusion, it was proven that polarization reduces unwanted reflected glare off surfaces.
