QUESTION #15 Polarisation
Two polarisers P₁ and P₂ are placed in such a way that the intensity of the transmitted light will be zero. A third polariser P₃ is inserted in between P₁ and P₂ at the particular angle between P₂ and P₃. The transmitted intensity of the light passing through all the three polarisers is maximum. The angle between the polarisers P₂ and P₃ is:

QUESTION #24 Diffraction and Interference
In a Young's double slit experiment, two slits are located 1.5 mm apart. The distance of screen from slits is 2 m and the wavelength of the source is 400 nm. If the 20 maxima of the double slit pattern are contained within the centre maximum of the single slit diffraction pattern, then the width of each slit is x × 10⁻³ cm, where x-value is ________.
