Look at the room lights through one of the polarizing filters provided

Describe how the filter affects what you see. Does rotating the filter have an affect?

Expert Solution & Answer
Check Mark
To determine

The changes made by the filter in the view.

Explanation of Solution

Introduction:

The polarized light is the one that have waves which vibrates only in one phase. A un-polarized can be transformed into a polarized light by using a polarizing filter. The process is called polarization.

When the room light are look through first polarizing filter they appear to be dimmer and their brightness is reduced by some amount because about half of the light is blocked as it passed through the filter. But at the same time the shape and dimension of the image is not distorted.

The rotation of filter will change the amount of polarized light passing through the filter. Because the filter will allow only light that is polarized in the direction perpendicular to the reflected light.

Conclusion:

Therefore, the room light are look through first polarizing filter they appear to be dimmer.

Learning Goal: To understand polarization of light and how to use Malus's law to calculate the intensity of a beam of light after passing through one or more polarizing filters. The two transverse waves shown in the figure(Figure 1) both travel in the +z direction. The waves differ in that the top wave oscillates horizontally and the bottom wave oscillates vertically. The direction of oscillation of a wave is called the polarization of the wave. The upper wave is described as polarized in the +x direction whereas the lower wave is polarized in the +y direction. In general, waves can be polarized along any direction. Recall that electromagnetic waves, such as visible light, microwaves, and X rays, consist of oscillating electric and magnetic fields. The polarization of an electromagnetic wave refers to the oscillation direction of the electric field, not the magnetic field. In this problem all figures depicting light waves illustrate only the electric field. A linear polarizing filter,…
