Question

light incident on a polarizer is then passed through a second polarizer. if the polarizer and the analyzer are perpendicular to each other, what can you say about the light waves emerging from the second polarizer?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

Answer 1

Indeed, this is one of the odd results in physics. A system of two polarizing filters arranged as shown below trasmits no light.

Answer 2

The intensity of light emerging from the second polarizer is zero.

Step-by-step explanation:

The angle between the axis of first polarizer and the second polarizer is 90°.

According to the law of Malus

`I = I_(0)* Cos^(2)\Theta`

where,
`I_(0)` be the intensity of incident light on first polarizer and I be the intensity of light emerging out from second polarizer.

The intensity of light emerging out from first polarizer is given by

`I_(1)=(I_(0))/(2)`

the inetnsity of light emerging out from second polarizer is given by

`I = I_(1)* Cos^(2)90`

`I = 0`

Thus, no light waves are emerging out from the second polarizer.
