Two polaroids P1 and P2 are placed with ...

Two polaroids `P_1` and `P_2` are placed with their axis perpendicular to each other. Un-polarized light `I_0` is incident on `P_1`. A third polaroid `P_3` is kept in between `P_1` and `P_2` such that its axis makes an angle `45^@` with that of `P_1`. The intensity of transmitted light through `P_2` is

A

`l_0/2`

B

`l_0/4`

C

`l_0/8`

(a) Using the phenomenon of polarization, show, how, transverse nature of light can be demonstrated. (b) Two polaroids P_(1) and P_(2) are placed with their pass axes perpendicular to each other. Unpolarised light of intensity 10 is incident on P1. A third polaroid P3 is kept in between P_(1) and P_(2) such that its pass axis makes an angle of 30^(@) with that of P_(1) . Determine the intensity transmitted through P_(1),P_(2) and P_(3) .

Unpolarised light of intensity I_0 passes through two polaroids P_1 and P_2 such that pass axis of P_1 . A third polaroid P_3 is placed between P_1 and P_2 with pass axis of P_3 making an angle 60^@ with that of P_1 . Determine the intensities of light transmitted by P_1, P_2 and P_3 .

Two polarioids P_1 and P_2 are placed in crossed positions. A third polaroid P_3 is kept between P_1 and P_2 such that the axis of P_3 is parallel to that of P_1 . How would the intensity of light (I_2) transmitted through P_2 vary as P_3 is rotated? Draw a plot of intensity 'I_2' vs the angle 'theta' between the axes of P_1 and P_3 . In which orientation will the transmitted intensity be (i) minimum and (ii) maximum?
