The angle of incidence at which reflected light is totally polarized for reflection from air to glass (refractive index $n$) is

Choose the $CORRECT$ statement from the following. Brewster's angle for a transparent medium is

At what angle of incidence $i$ will the light reflected from water be completely plane-polarized (in $^\circ$)? (Given refractive index of water $\mu = 1.33$)

$A$ person lives in a high-rise building on the bank of a river $50\, m$ wide. Across the river is a well-lit tower of height $40\, m$. When the person,who is at a height of $10\, m$,looks through a polarizer at an appropriate angle at light of the tower reflecting from the river surface,he notes that the intensity of light coming from a distance $X$ from his building is the least,and this corresponds to the light coming from light bulbs at height $Y$ on the tower. The values of $X$ and $Y$ are respectively close to (refractive index of water $\simeq \frac{4}{3}$)

Light is incident at an angle $i$ on a glass slab. The reflected ray is completely polarised. The angle of refraction is

$A$ transparent medium shows a relationship between $\sin i$ and $\sin r$ as shown in the graph. If the speed of light in vacuum is $c$,the Brewster angle for the medium is: (in $^{\circ}$)
