Answer:
not
medium
Step-by-step explanation:
Light radiation travels as a wave and does not require a medium for travel. Like all electromagnetic radiations, light does not need medium particles for its propagation.
- Light radiation can pass through a vacuum of space without particles.
- This carries energy from one point to another in this region of space.
- Such form of waves are electromagnetic waves.
- Electromagnetic waves can be propagated through vacuums.
