An unpolarized light beam travelling in air is incident on a medium of refractive index $1.73$ at Brewster's angle. Then
- Areflected light is completely polarized and the angle of reflection is close to $60^{\circ}$
- Breflected light is partially polarized and the angle of reflection is close to $30^{\circ}$

View Solution$A$ camera equipped with a polariser is placed on a mountain to record only the reflected image of the sun from the surface of a sea,as shown in the figure. If the sun rises at $6.00 \, AM$ and sets at $6.00 \, PM$ during the summer,then at what time in the afternoon will the recorded image have the lowest intensity? Assume there are no clouds and the intensity of the sun at the sea surface is constant throughout the day. (Refractive index of water $= 1.33$)
The polarising angle for a transparent medium is $\theta$,and $v$ is the speed of light in that medium. Then the relation between $\theta$ and $v$ is (where $c$ is the velocity of light in air).
The Brewster angle for air to glass transition of light is (Refractive index of glass $= 1.5$).
The refractive index of a medium is equal to the tangent of the polarizing angle. This is known as:
