A He-Ne laser uses Brewster windows of glass refractive index 1.5 to suppress reflection. With the geometry shown, choose the conditions required for zero reflection of the polarized laser beam.

Select all that apply

• Option A

  The angle made by each of the glass plate with the direction of light beam should be the same.

• Option B

  The angle between the light beam and the glass plate surface should be tan⁻¹(2/3).

• Option C

  The incident beam should be plane polarized with the plane of electric field same as the plane of paper.

• Option D

  The incident beam should be plane polarized with the plane of electric field perpendicular to the plane of paper.
