Polarization | MCQs

Explanation

Transverse waves involve oscillations perpendicular to the direction of travel and can be polarized, while they do not necessarily require a medium to travel (e.g., light waves).

Explanation

Polarization is a property of transverse waves, where the direction of vibration can be oriented in various directions.

Ultrasonic waves are longitudinal waves and cannot be polarized.

Explanation

The electric field due to a positive charge points away from the charge, i.e., radially outward.

Field lines show the direction a positive test charge would move.

Explanation

Explanation

Transverse waves oscillate perpendicular to the direction of the wave's travel and can exhibit polarization.

Explanation

When a dielectric sheet is placed between two charges, the electrostatic force between them will "decrease" because the presence of the dielectric reduces the electric field strength between the charges, thus decreasing the force experienced by them.
