JEE AdvancedPhysicsWave OpticsNumerical+4 / −1
A point source S\mathrm{S}S emits unpolarized light uniformly in all directions. At two points A\mathrm{A}A and B\mathrm{B}B, the ratio r=IA/IBr=I_A / I_Br=IA​/IB​ of the intensities of light is 2 . If a set of two polaroids having 45∘45^{\circ}45∘ angle between their pass-axes is placed just before point B\mathrm{B}B, then the new value of rrr will be ‾\underline{\hspace{2cm}}​.
