Which of the following is not correct?

Options

A. The fundamental sources of electromagnetic waves are accelerating electric charges.
B. Electromagnetic waves carry momentum and hence, can exert pressure on surfaces.
C. Electromagnetic waves carry energy.
D. Electromagnetic waves are longitudinal waves.

Answer

D

Explanation

Longitudinal waves are those waves in which the vibration or displacement takes place in the direction of propagation of the waves, for example, sound waves. Electromagnetic waves are transverse waves because the electric and magnetic fields of an electromagnetic waves are perpendicular to each other and perpendicular to the direction of wave propagation.
