Question

What best describes the angle between a changing electric field and the electromagnetic wave produced by it? (2 points)

Answer 1

Answer:

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.

• A shifting electric field generates a changing magnetic field that in effect causes a changing electrical field.
• This means the source has generated a perpendicular to each other, shifting electrical and magnetic fields that travel away from the source.

• Electromagnetic (EM) waves shift electrical and magnetic fields, conveying energy and momentum across space.

According to this question, other options are incorrect.

Answer 2

A) always equal to a right angle
