282822 Light from sodium lamp is made to pass through two polaroids placed one after the other in the path of light. Taking the intensity of the incident light as \(100 \%\), the intensity of the out coming light that can be varied in the range

282823 The glass prisms \(P_1\) and \(P_2\) are to be combined together to produce dispersion without deviation. The angles of the prisms \(P_1\) and \(P_2\) are selected as \(4^{\circ}\) and \(3^{\circ}\) respectively. If the refractive index of prism \(P_1\) is 1.54 , then that of \(P_2\) will be
