Unpolarised light is incident on the boundary between two dielectric media, whose dielectric constants are 2.8 (medium-1) and 6.8 (medium-2), respectively. To satisfy the condition that the reflected and refracted rays are perpendicular to each other, the angle of incidence should be tan⁻¹[(1 + 10/θ)¹ᐟ²]. The value of θ is _____. [Given for dielectric media, μ(r) = 1]
