What is brewster's angle for an air-glass n = 1.58 surface

n₂ = index of refraction of glass = 1.58

n₁ = index of refraction of air = 1

θ = Brewster's angle

Brewster's angle is that incident angle at which the the reflected light from the interface of two medium is completely polarized.

Brewster's angle is given as

θ = tan⁻¹(n₂ /n₁ )

θ = tan⁻¹(1.58/1 )

θ = 57.7 deg

hence the Brewster's angle comes out to be 57.7 deg

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
