Question

Which phenomenon confirms the transverse nature of electromagnetic waves?

• A. Interference
• B. Diffraction
• C. Polarization
• D. Reflection

Hint:

{Polarization occurs only in transverse waves}. Its observation proves that light is a {transverse electromagnetic wave}.

Answer 1

The Correct Option is C

Concept: Polarization is a phenomenon in which the vibrations of a wave are restricted to a particular direction.
Step 1: Understand wave behavior.} Only transverse waves can exhibit polarization because their oscillations occur perpendicular to the direction of propagation.
Step 2: Implication for electromagnetic waves.} When light waves are polarized, it proves that their electric field oscillates in directions perpendicular to the direction of propagation.
Step 3: Conclusion.} Thus, the phenomenon that confirms the transverse nature of electromagnetic waves is polarization.
