Which one of the following is NOT true for an electromagnetic wave?
general-sciencephysics-light-electricity
- AElectromagnetic wave transports energy and momentum
- BElectromagnetic wave can be polarized and reflected
- CElectromagnetic wave is longitudinal
- DElectromagnetic wave propagation is described by the varying electric and magnetic fields
Explanation
Electromagnetic waves transport energy and momentum (A true), can be polarised and reflected (B true), and consist of oscillating electric and magnetic fields (D true). They are transverse waves, not longitudinal - so C is the NOT-true statement.
