Question

if the particles of the medium are vibrating in the same direction as the waves energy, then the wave is a ______ wave. a light b electromagnetic c transverse d longitudinal

Explanation:

To solve this, we recall wave types:

• Light and electromagnetic waves are transverse (vibrations perpendicular to energy direction).
• Transverse waves have vibrations perpendicular to wave energy direction.
• Longitudinal waves (e.g., sound) have particles vibrating parallel (same direction) to wave energy direction. So the correct type is longitudinal.

Answer:

d. longitudinal
