Quiz on Polarization of Waves

Which type of polarization occurs when the electric field oscillates in a single direction?

• Circular polarization

• Elliptical polarization

• Linear polarization

What is the definition of polarization in electromagnetic waves?

• The absorption of electromagnetic waves in a medium

• The locus traced by the tip of the E vector (in the plane orthogonal to the direction of propagation) at a given point in space as a function of time.

• The change in frequency of electromagnetic wave

Which statement is true about linear polarization?

• It has electric field components in two perpendicular directions with unequal amplitudes and phase difference.

• It has electric field components in two perpendicular directions with equal amplitudes with phase difference of 90 degrees.

• It has electric field components in two perpendicular directions with arbitrary amplitudes with phase difference zero or 180 degrees.

Which statement is true about circular polarization?

• It has electric field components in two perpendicular directions with unequal amplitudes with phase difference of 90 degrees.

• It has electric field components in two perpendicular directions with arbitrary amplitudes with phase difference zero or 180 degrees.

• Represents transmitted power

• Is the power loss due to finite conductivity

• Is the electrical stored energy
