Solution:

Which of the following is not a property of Elliptical Polarization?

Consists of two perpendicular waves.

The amplitude of both the waves are equal.

The EM waves differ in phase by 90°

Circular and Linear polarization are special cases of elliptical polarization.

Solution:

Which of the following statements is/are true about Faraday's experiment on electric flux with concentric spheres?

The displacement flux from the inner circle to the outer circle is independent of the medium between them.

The displacement flux is called electric flux.

The electric flux is directly proportional to the charge on the inner sphere.

All of the above statements are true.
