Polarization

The axis of two Nicol prisms are parallel to one another. One of the two Nicols is rotated through an angle of 60 degrees, the ratio of intensity transmitted before and after rotation

• 2

• 1

• 4

• 1:4

Amplitude of unpolarized light incident on polarizer is 'a'. What will be the amplitude of polarized light transmitted, will be __________ {Sqrt = Square root}

• a/2

• 3a/2

• a/sqrt(2)

• Sqrt(3)/2

What is the primary cause of polarization in dielectrics?

• High temperature

• Mechanical stress

• The presence of an electric field

• Immersion in a magnetic field

To which term of reference does the following description refer to?

"an unequal distribution of an electrical charge"

• Polar

• Nonpolar

• Both

Answer explanation

The unequal distribution "or sharing" of electrons results in - one side of a Polar Covalent Bond being partially negative while the other side is partially positive.
