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.
