POLARIZED LIGHT LAB REPORT
EXPERIMENT # 5
June 27, 2014
PHYS 1417
ABSTRACT
Ordinary light such as that from a light bulb is a form of wave motion that consists of electrical and magnetic fields that vibrate at right angles to the direction of travel of a light beam. Light waves that vibrate in a single plane are called polarized light waves. Such waves can be produced by passing light through polarizing filters. The experiment conducted was composed of crossed polarizers both qualitative and quantitative, polarization by reflection and of skylight were also tested by using a polarization filters. In conclusion, it was proven that polarization reduces unwanted reflected glare off surfaces.
HYPOTHESIS
If and only if a lens is polarized then regardless of orientation of incoming light waves light coming out of the polarized lens is always polarized in the direction of the polarization axis.
MATERIALS
one flash light or desk lamp two cable jumpers one laser pointer one multi meter digital one protractor one capacitor set, PK, 4pcs, Capacitor LED, Diode, Photocell two clothespin one polarizing cards (2)-PK
PROCEDEURES
PART I
First one polarizing filter was placed on top of the other so that light is transmitted. Then with two filters were put together and aligned so that light passed through them, looking through them at a bright light in this case a flash light was used. Then slowly one of the filters was rotated through 360o while keeping the other one still. Observations were then recorded.
OBSERVATIONS: From my observation in part one by placing the two filters together one in front of the other and slowly rotating one of the filters I notice that light between them became brighter as one filter was being rotated then the light became a dark blue shade.
PART II -
In part two of the experiment one polarizing filter was placed on top of the other so that light was transmitted. Next cloth pins
