Question

which of the following is radiation that can travel through empty space in a vacuum?
○ longitudinal waves
○ transverse waves
○ electromagnetic waves
○ mechanical waves

Explanation:

Longitudinal and mechanical waves require a medium (e.g., air, water) to travel, so they cannot move through a vacuum. Transverse waves include both mechanical (e.g., water waves) and electromagnetic waves; not all transverse waves can travel in a vacuum. Electromagnetic waves (e.g., light) propagate via oscillating electric and magnetic fields, needing no medium, so they travel through empty space.

Answer:

C. electromagnetic waves
