When a plane polarised light is passed through an analyser and analyser is rotated through 90o, the intensity of the emerging light

EASY
IMPORTANT

Plane _____ light is made up of waves with the same direction of vibration for all of them. Light can be polarised through reflection or passing through filters, such as crystals, that transmit vibration in one plane but not in others.

EASY

How can light be Polarised with a Polaroid?

HARD
IMPORTANT

Three circularly shaped linear polarisers are placed coaxially. The transmission axis of the first polariser is at 30°, the second one is at 60° and the third at 90° to the vertical all in the clockwise sense. Each polariser additionally absorbs 10% of the light. If a vertically polarised beam of light of intensity I=100 W m-2 is incident on this assembly of polarisers, then the final intensity of the transmitted light will be close to:

Two polaroids are oriented with their principal planes making an angle of 60°. The percentage % of incident unpolarized light which does not pass through the system is

EASY
IMPORTANT

An unpolarized light beam is incident on the polarizer of a polarization experiment and the intensity of light beam emerging from the analyzer is measured as 100 Lumens. Now, if the analyzer is rotated around the horizontal axis (direction of light) by 30° in clockwise direction, the intensity of emerging light will be Lumens.
