Which one of the following is NOT true for an electromagnetic wave ?

Electromagnetic wave transports energy and momentum
Electromagnetic wave can be polarized and reflected
Electromagnetic wave is longitudinal
Electromagnetic wave propagation is described by the varying electric and magnetic fields
This question was previously asked in
UPSC CAPF – 2019
Electromagnetic waves are transverse waves, not longitudinal. In a transverse wave, the oscillations of the wave are perpendicular to the direction of wave propagation.
– Electromagnetic waves consist of oscillating electric and magnetic fields that are perpendicular to each other and to the direction of propagation.
– They transport both energy and momentum.
– Being transverse waves, they can be polarized. They also undergo reflection, refraction, diffraction, and interference.
– Longitudinal waves, such as sound waves in air, involve oscillations parallel to the direction of propagation.
– The statement that electromagnetic wave propagation is described by varying electric and magnetic fields is fundamental to Maxwell’s equations, which govern their behaviour.
