Explain how you could use a single polarizing filter to detirmine whether light from a given source is polarized or unpolarized: what would you do with the filter? What would you see if the light was polarized vs unpolarized?

Answer #1

When an unpolarized light with intensity Io passes through a polarizer ,it polarizes the light and and intensity of light becomes Io/2 after transmitting the polarizer.

When a polarized light with intensity Io passes through a polarizer its intensity after transmitting is given by relation

I = Io (cos)^2

where is the angle between polarization axis of polarizer and the line along which light is polarized.

By measuring the transmitted intensity we differentiate whether light was unpolarized or polarized.

An unpolarized light bulb is dimmed by a stack of three polarizing filters. The middle filter is rotated 21.6 ∘ from the first filter, and the final filter is rotated 56.8 ∘ from the first filter. A light intensity of 71.5 W/cm2 exits from the stack of all three filters. The intensity can be increased and decreased by rotating the middle filter to other angles. What is maximum light intensity that can be obtained?

You have an experimental setup consisting of a light source, three polarization screens, and a light sensor. Logger pro records the intensity [lux] of the light incident to the light sensor vs. the angle of the polarization screen. The initial intensity of your light source (no polarizing screens) is  = 784 lux. Assume zero ambient light during the entire experiment. a) (4 pts) If you place ONE polarizing screen between the light source and light sensor, what is the expected intensity...

Use one of your polarizing filters to look at the sky at 90 degrees to the direction of the Sun. Never look directly at the Sun. Look at different regions of the sky and notice if the intensity of the light changes as you rotate the polarizer. Record your observations. Are your sunglasses polarized? How do you know for certain?
