What best describes the angle between a changing electric field and the electromagnetic wave produced by it? (2 points) a) always equal to a right angle b) always less than a right angle c) varies from parallel to perpendicular d) varies from perpendicular to parallel

Option (A) is the correct answer of this question.

Explanation:

The angle between a changing electric field and the induced electromagnetic wave is always equal to the right angle. The electrical field, the magnetic field and the EM wave are perpendicular. This gives its transverse form to the electromagnetic waves.

According to this question, other options are incorrect.

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?
