Questions Related to polarisation of light
A parallel beam of monochromatic unpolarised light is incident on a transparent dielectric plate of refractive index $\displaystyle\frac{1}{\sqrt{3}}$. The reflected beam is completely polarised. Then the angle of incidence is
Which of the following phenomena can be demonstrated by light. But not with sound waves in an air column ?
If the incident light is linearly polarised, then the directional distribution of emitted electrons will peak in the direction of
Assertion: Radio waves can'be polarised.
Reason: Sound waves in air are longitudinal in nature.
A parallel beam of natural light is incident at an angle of 58$^{\circ}$ on a plane glass surface. The reflected beam is completely linearly polarized(tan 58$^{\circ}=$1.6). The angle of refraction of the transmitted beam and the refractive index of the glass are :
If the critical angle of a crystal is $45^{\circ}$, the polarizing angle is :
When an unpolarized light of intensity ${I} _{0}$ is incident on a polarizing sheet, the intensity of the light which does not get transmitted is:
When the angle of incidence on a material is ${60}^{o}$, the reflected light is completely polarised. The velocity of the refracted ray inside the material is
When unpolarised light beam is incident from air onto glass $(n=1.5)$ at the polarising angle.
The solar glare of sunlight bouncing off water or snow can be a real problem for drivers. The reflecting sunlight is horizontally polarized, meaning that the light waves oscillate at an angle of $90^o$ to a normal line drawn perpendicular to the Earth. At what angle relative to this normal line should sunglasses be polarized if they are to be effective against solar glare?
