If the angle between the pass axis of the polarizer and the analyzer is 45, the ratio of the intensities of original light and the transmitted light after passing through the analyzer is
The angle between the pass axis of polarizer and analyzer is $45^{\circ}$. The percentage of polarised light passing through analyzer is:
When ordinary light is made incident on a quarter wave plate, the emergent light is:
Unpolarized light is incident on a plane glass surface. The angle of incidence so that reflected and refracted rays are perpendicular to each other, then:
The velocity of light in air is $3 \, \times \, 10^8 \, m \, s^{-1}$ and that in water is $2.2 \, \times \, 10^8 \, m \, s^{-1}$. The polarising angle of incidence is:
At what angle of incidence will the light reflected from glass $( \mu \, = \, 1.5)$ be completely polarised
The critical angle of a certain medium is sin−1(35)sin−1(35) The polarizing angle of the medium is:
In the case of linearly polarized light, the magnitude of the electric field vector
Light from sodium lamp is made to pass through two polaroids placed one after the other in the path of light. Taking the intensity of the incident light as 100%, the intensity of the out coming light that can be varied in the range:
If the critical angle be $ \theta$ , then the Brewster's angle is
