What angle should the beam made with the vertical, so that after passing through the analyzer, it’s intensity should become 0.86 times the initial intensity?

Light polarization is a property of transverse waves that defines the geometrical orientation of oscillations. In a transverse wave, the direction of oscillation is perpendicular to the direction of motion of the wave.

Polarized light is made up of waves that vibrate in a single plane.

Polarization is an important property of light that affects even those optical systems that do not explicitly measure it. The polarization of light affects the focus of laser beams, influences the cut-off wavelengths of filters, and can be important to prevent unwanted back reflections. 
Polarization of light can be used to encode quantum information. Polarized sunglass lenses reduce light glare and eyestrain. Because of this, they improve vision and safety in the sun.
