A beam of light passes through a polarizer and then
ananalyzer. In this process, the intensity of the lighttransmitted
is reduced to 10% of the intensity incident on theanalyzer. What is
the angle between the axes of the polarizerand the analyzer?

Respuesta :

Answer:

Angle between the polarizer and analyzer will be 18.43°

Explanation:

Let the original intensity of light is [tex]I_0[/tex]

It is given that when light is passed through through a polarizer  its intenity is decreased by 10 %

So after polarization new intensity of light [tex]I=I_0-0.1I_0=0.9I_0[/tex]

We know that when light is passed through a polarizer its intensity is given by

[tex]I=I_0cos^2\Theta[/tex]

[tex]0.9I_0=I_0cos^2\Theta[/tex]

[tex]cos^2\Theta =0.9[/tex]

[tex]cos\Theta =0.9486[/tex]

[tex]\Theta =18.43[/tex]

So angle between the polarizer and analyzer will be 18.43°
