Answer Key : (a) -

(a)

No light is emitted from the second polaroid, so  and  are perpendicular to each other

Let the initial intensity of light is . So Intensity of light after transmission from first polaroid

Intensity of light emitted from

Intensity of light transmitted from last polaroid  from



Next Question :

Two beams of light of intensity  interfere to give an interference pattern. If the ratio of maximum intensity to that of minimum intensity is then  is

a)

5/3

b)

4

c)

d)

16
