Explanation:
Detailed explanation-1: -Malus’ law states that the intensity of plane-polarized light that passes through an analyzer varies as the square of the cosine of the angle between the plane of the polarizer and the transmission axes of the analyzer.
Detailed explanation-2: -A well-known special case of Malus’ law is the situation where the plane passed through the polarising filter is oriented perpendicular to the plane of polarisation of the incident light. In such a case, =90∘ and hence I=0; the polarising filter, therefore transmits no light.
