Question

ALLEN 114 When unpolarized light beam is incident from air onto glass n 1 5 at the polarizing angle 1 Reflected beam is 100 percent polarized 2 Reflected and refracted beams are partially polarized 3 The reflected and refracted ray will not perpendicular to each other 4 All of the above WO0115 115 When the angle of incidence on a material is 60 the reflected light is completely polarized The velocity of the refracted ray inside the material is in ms 1 3 x 10 3 3 x 10 10 2 4 0 5 x 10 WO0116 116 A polaroid is placed at 45 to an incoming light of intensity 1 Now the intensity of light passing through polaroid after polarisation would be 1 L 2 1 2 3 1 4 4 Zero WO0117 117 Plane polarised light is passed through a polaroid On viewing through the polariod we find that when the polariod is given one complete rotation about the direction of the light one of the following is observed 118 Pre Medical Physics 107 1 The intensity of light gradually decreases to zero and remains at zero 2 The intensity of light gradually increases to a maximum and remains at maximum 3 There is no change in intensity 4 The intensity of light is twice maximum and twice zero WO0118 Polarised glass is used in sun glasses because 1 It reduces the light intensity to half on account of polarisation 2 It is fashionable 3 It has good colour 4 It is cheaper W00119 119 When a plane polarised light is passed through an analyser and analyser is rotated from 0 to 90 the intensity of the emerging light 1 Varies between a maximum and minimum 2 Becomes zero 3 Does not vary 4 Varies between a maximum and zero WO0120 120 When an unpolarized light of intensity I is incident on a polarizing sheet the intensity of the light which does not get transmitted is 1 Zero 2 1 3 1 4 1 WO0121
