1.	a beam of natural light falls on a system of 5 Polaroid s which are arranged in succession such that the pass axis of each polarid is turned through 60 degree with respective to the preceding one . the fraction of incident light that passes through the system
Answer» ction of incident light that passes through the system is given below: Explanation:Given :- Beam of natural light falls on a system of 5 Polaroids. The pass AXIS of each polarid is turned through 60 degree After passing through I st polaroid, I = Io / 2 After passing through next 4 polaroids I = Io / 2 . { cos^2 (60) }^4 I = Io / 2 . ( 1 / 4 )^4 I = Io / 2 . 1 / 216 I = Io / 512 hence, I = 1 / 512 Therefore, the fraction of incident light that passes through the system is 1 / 512.For more:A particle of mass 200 g is whirled into a vertical circle of radius 80 cm USING a massless string the SPEED of the particle when the string makes an angle 60 with vertical line is 1.5 m/s the tension in the string at this POSITION isbrainly.in/question/1434817A ball is dropped from a high rise platform at t = 0 starting from rest.
