Assessment: WAEC SSCE - Physics - 2022 (Objective) Subject: Physics

Question 1 Report

Which of the following statements-about electromagnetic waves is not correct?
Answer Details
The statement that is not correct is: "They are longitudinal". Electromagnetic waves are actually transverse in nature, which means that the electric and magnetic fields oscillate perpendicular to the direction of wave propagation. Longitudinal waves, on the other hand, have oscillations parallel to the direction of wave propagation. The other three statements are correct: electromagnetic waves carry energy as they travel through space, they travel with the speed of light, and the electric and magnetic fields are at right angles to each other.
