Plane polarised light is passed through a polaroid. On viewing through the polaroid we find that when the polariod is given one complete rotation about the direction of the light, one of the following is observed
Answer & explanation
Correct answer: option 1
For single slit diffraction pattern $d \sin \theta=\lambda$ (d= slit width)
Angular width = $2 \theta=2 \sin ^{-1}\left(\frac{\lambda}{d}\right)$
It is independent of D i.e. distance between screen and slit
