Question

According to the text, what is the relationship between the electric field, magnetic field, and direction of travel in an electromagnetic wave like light?
Options
A All three are parallel to each other.
B The electric field is parallel to the direction of travel, and the magnetic field is perpendicular.
C The electric and magnetic fields are at right angles to each other and moving perpendicular to the direction of travel.
Correct Answer
D The electric and magnetic fields are perpendicular to each other, and both are parallel to the direction of travel.
Correct Answer

Option C is the correct answer.

Detailed Explanation

The text states, 'Light is an electromagnetic (e.m) wave. It consists of electric and magnetic fields at right angles to each other and moving perpendicular to the direction of travel of the light wave.'

Hint

The first sentence under 'Polarization of Transverse Waves' describes the nature of light.
